I found the user accounts "Binksternet", "Mark in wiki", "Materialscientist", "Richard3120", ''Kellymoat", ''Jusdafax'', ''RoCo'' and ''Jim1138'' so far. Will continue to update once I find more.

Agreed 100%. Classifying artists is a pointless thing to do

A little observation here, just finding out that there are admins who are reverting edits using 8 accounts, which were found out to be done within the exact same day and existed for around 5 months as the "latest revision"
