as you know, the artist must have been a mod so they can approve their own images.
The artist is skilled at drawing with the imgflip draw tool so it can't be DarthTricea or inkmatas, who prefer to draw on paper.
a lot of people are blaming LuigiGuy because the posts involve blobler and not many people post about him except luigiguy. However, he isn't a mod and no mods would have approved those "anonymous" images.
I was absent from the site at the time the images were posted and the stream was created, and I can't draw well with the imgflip draw tool either.
Dr Bob is certainly a possibility, but like inkmatas and darthtricea he can't draw with the imgflip draw tool very skillfully and although he is toxic sometimes, he would otherwise have no reason to post them.
YourLocalMemer69 might be the culprit as he is skillful with the imgflip draw tool and the posts on the gore stream involve redi and jhonn. However, he wouldn't have any reason to do this anyway and he hates r34.
Christmas_cat can draw very well with the imgflip draw tool but would have no motive either, and he was only just added as a mod.
Which leaves me with my final two culprits.
Eggy_head was already doing rule 34 and smash or pass on this stream and would probably do it, since his motive is (as always) to do a little trolling. He can also draw skillfully with the imgflip draw tool.
But my final culprit is void_the_christmas_umbreon, who is probably the most suspicious of them all. The artist's account's previous username was similar to void's and he can draw skillfully. His motive in probably to cause drama and tension as he called out the artist and his stream already.
But the artist has followed all the boss fights streams, and there are only a few people that have done that.. (I'm still yet to find them and double check)
