Sanctioned Suicide is a user-account forum, sometimes wiki, and informational website founded by self-described 'blackpilled incels' and has been reported as facilitating the suicide of a broad population with curable conditions, including minors and without a license. Some Wikipedians (including Wikipedia admins) have been ruthlessly trying to whitewash the site and it's 'blackpilled incel' founders/owners through various hijinks, mostly unsuccessfully, but sometimes successfully.
The most commonly cited suicide method in, "goodbye threads", on Sanctioned Suicide is the meat preservative sodium nitrite, according to an investigative article by a few Pultizer Prize winning journalists. They did statistical analysis on all the goodbye threads.

'Serge' was reportedly the Sanctioned Suicide co-founder named, 'Diego Galante' and is seemingly aware that the most common suicide method on the site is painful. It was the most common method on his forum before and after he claimed to resign in 2021.

Galante might have actually left in 2021. The other founder, named Small, probably didn't. The social media for his site has recently promoted the chemical.

Galante and Small also started a body dysmorphia discussion forum called Looksmax, as well as a blackpill incel forum called incels(dot)is. Small still openly runs incels(dot)is as "Master". Accounts from the body dysmorphia forum and blackpill incel forum are reportedly encouraged to take their lives and funneled to the SanctionedSuicide forum with the same server admin. I have almost two dozen archives of this happening, and can post it if people want. Went far beyond the joking that was seen on Wizchan. Was fine with the prior Usenet SS forum, but no one really is fine with this current one except some on Wikipedia of course.
In case you think these are innocent and clueless SS founders, held captive by their community, here is Small's other social media

Wikipedians
I'll list off the supporters and half-defenders of this forum on Wikipedida
Supporters of SS on Wikipedia
1) Kevinsanc was an account that was active in daily deletions of the SS founders activities on the site, and introduced many dishonest edit summaries, even to the point of a half-defender of the site, named Freedom4U trying to sanction them for it. The Wikipedia admins mostly ignored the relevant COI board debate and didn't sanction KevinSanc. This Kevinsanc account is inactive after they were threatened to be reported to law enforcement for dishonest edit summaries involving dead children. Wikipedia admins were notified off-wiki of this account, and as mentioned earlier, they still did nothing to sanction Kevinsanc.
Wikipedia admins didn't even sanction him after he lied that the main minor death subject of multiple, properly cited articles, weren't in the articles. (They are, it takes 5 seconds to find it)
They claimed they couldn't find it after an hour of looking!, Also their recommendation for the IP to edit himself was done in bad faith as the article was clearly locked at the time.

https://en.wikipedia.org/wiki/Talk:Sanc ... st_edits_2
Here's an excerpt about this particular minor death Kevinc and Freedom4U have been rigorously reverting, and who Kevinsanc says he can't find in cited articles in the sentence which used to be in mainspace.

https://www.pbs.org/newshour/show/why-a ... ins-active
That death is also a main subject of two NYTimes pieces, including the one he said he read for an hour.

2) Nikados, who bothered to register a whole account just to change the accent direction in Diego's name to the wrong direction with a false edit summary
3) Various IP editors from SS, who have been posting suicideality in edit summaries, along with provably false information about the site, etc. WIkipedia admins, many who patrol the page, did not ban any meaningful amount of these IPs inserting false edit summaries or generic vandalism. Virtually all of this occured the first few weeks of the page and so are buried in the history, but can be found. Now IPs are mostly detractors of SS instead.
Half-defenders of SS on Wikipedia
1) Freedom4U, who has stated on the talk page dishonestly that they don't think the news reporting of the deaths disparage the site. They use that opinion to establish whitewashing verbiage on the article throughout. For reference, here are some deaths referenced in RS news articles which are solely on Sanctioned Suicide, which Freedom4U doesn't consider disparaging, only 'controversial'. They are often the top Google results for the forum.

Thankfully, they are not always a supporter because they tried to sanction Kevinsanc and refused to let the SS IPs remove all references to encouragement.
Although this was good, they are not an overall an honest person on the topic. They've have removed references to the most systemic examples of suicide encouragement on the site, particularly by removing sentences reinforcing the journalists statements that the site facilitates suicide.
Conveniently, Freedom4U has repeatedly removing a sourced sentence pointing out Diego (a founder) refused to let members post their contact info, so as to commit suicide more efficiently. They also removed a cited sentence where an Australian esafety commissioner was explicitly saying the site itself incites suicide. They also removed cited sentence where multiple journalists are referenced as saying the site facilitates suicide in RS.
Freedom4U has repeatedly refused to acknowledge on talk that the site itself ever facilitated suicide. Nevermind that the journalists explicitly state that in RS as linked above, here's Diego doing exactly that, facilitating suicide by running a huge pact thread and telling people not to post contact info in it.

https://archive.md/cPIz1#selection-599.84-599.85
Freedom4U has said in at least one edit summary that their initial draft of the page was inspired by someone they initially took as honest and reliable on 8chan.
2) At least 5 coordinated Wikipedia admins Not sure if worth naming them at this point, as their involvement was brief. They refused to sanction a wide array of people putting in false or legally concerning edit summaries, sometimes instead preferring to revdelete rather than sanction the user or IP. Additionally multiple Wikipedia administrators have removed the topic wholesale from relevant pages before, by secretly coordinating with other admins. On one page they reverted an IP coming from a US Fed office.
Detractors of SS on Wikipedia
1) Fredrick Brennan. He started 8chan, but it was stolen from him by some deranged right-winger. He's known for his role in internet cultlure and condemnation of toxic elements of it, has re-opened a GA review of the page after Freedom4U's latest whitewashing of SanctionedSuicide. He has also seemingly been distancing the site from the Usenet one.
He appears to have created his GA-review unprompted.
In his re-opened GA review Brennan states the article is "too sympathetic to the viewpoints of Galante and Small"

2) DFlhb A wikipedian who challenged Freedom4U's framing of the site, just to be randomly reverted. So far, DFlhb has totally given up, handing control over to someone who disagrees with them.
3) At least 6-7 good-standing Wikipedia veterans who posted in the SS URL RFC along with two or three IP ranges, and also alleged banned editors
All the SS detractors are actually the majority, and why the URL RFC to censor the domain succeeded. Although some SS detractors, like Brennan arrived after the RFC and can't say what their opinion on the URL RFC Is.
So why does so much of the article look like it was written by supporters when they are inactive? Two reasons: Wikipedia admins refusing to sanction the dishonest people who Freedom4U took to the COI board. And the second reason being Freedom4U, who seems to have just wanted to whitewash the site in a less obvious or accountable way.
