After digging through the archives, I think I've pieced together the "Tonyo" situation that's been popping up in the report queue in /ic/ for the past couple of weeks. I originally was clearing the related reports, but my current opinion is that we should be cleaning up the board by hitting posters with trolling.
tl;dr This whole thing is a massive LARP to get people to nuke the art resources they've downloaded.
I found this post, which helped me go back into the archive and figure out the chronology of things:
https://boards.fireden.net/ic/thread/5350027/#5351857 -- someone gives a rough estimate of the quote from the person who uploaded the MEGA in question, leading me to determine:
The video course MEGA is the one that got taken down (again) in mid-April.
https://boards.fireden.net/ic/thread/5181374/ -- OP reposts the MEGA in February, stating that he has not been the person who consistently reuploads the contents and that he won't reupload it again after this point since it gets taken down frequently
https://boards.fireden.net/ic/thread/5180339/#5183186 -- similar post from presumably the same person
https://boards.fireden.net/ic/thread/5265226/ -- new thread edition in March
https://boards.fireden.net/ic/thread/5265226/#5332490 -- from the same thread, the first post noticing that this iteration of the MEGA was taken down -- note, the date is Tue 13 Apr 2021 02:42:21 (4chan time)
https://boards.fireden.net/ic/thread/5332551/ -- thread goes up shortly after (Tue 13 Apr 2021 03:44:26) to start reassembling the contents from the MEGA
https://boards.fireden.net/ic/search/text/tonyo/order/asc/ -- the first mention of "Tonyo" on /ic/ EVER is Tue 13 Apr 2021 07:04:49
https://boards.fireden.net/ic/thread/5332551/#5332774 -- this is that first mention of Tonyo, which blows up with a shitload of replies
