Here, I've talked to him for a while, and we should make things clear: The reason why he asked for those requests has nothing to do with any sort of fetishes. He just purely enjoys big-sized Cream as a character and liking a character being big doesn't necessarily mean that there's some sort of dirty intentions or fetishes behind. I know you're not 100% sure that he has this kind of fetishes or not, but people in the comments seemed to have taken your words for granted and though that he is that sort of person, and it really hurts him.

Also, I kinda wanna assume there are some artists that had those fetishes in mind when they're taking those requests that didn't have the fetishes in mind, so some of the pictures came out wrong, but that's just an assumption, I don't really want to accuse anyone for having such fetishes and neither should anyone else do so.

And about the groups, I think they allowed those requested pics to be there for a reason. Y'know, there must be some kind of approval before the pics can be legitimately added to the group. If you don't really like the picture, you don't have to. Just delete whatever notification about it and enjoy the rest of the pics you like. There might be other people that really like it (not necessarily in a weird or dirty way, mind you), so just let 'em enjoy what they like while you enjoy what you like.
