Ever since Fandom purged some of the sperglands from their site, most notably Pooh's Adventures, most of them decided to move to Miraheze to continue their fanonfaggotry. The only upside to Miraheze is that it doesn't have a million fucking ads spawning everywhere on the page every second unlike Fandom. The wikis I found out got closed were Supernanny Fanon, Sexypedia, Peppa Pig Fanon and SpongeBob Fanon (I loved that one

).
One thing the Peppa Pig Fanon Wiki REALLY loves to do is a little genre called "free-add comics". Basically, someone adds a gallery with character PNGs/JPEGs and the caption is dialogue. So on and so forth. Since most of the free-add comics there are more often than not started by children, shit can get pretty spergtastic fast. Most of the free-add comics I've seen have some genres of autism I can recognize right off the bat (GoAnimate, Alphabet Lore, BFDI, Numberblocks, baby shows, etc). MS Paint drawings as well.
One of the largest pages on the wiki is the
Community Comic Book. It's basically a free-add comic without the free-add aspect (despite being a
COMMUNITY comic book). Its last chapter,
Checkpoint 5, has remained stagnant since September 19th of last year. The only edits that are happening now are reverts (because god forbid someone tries to join the "community" in question

)
The notice on Checkpoint 5 said:
Contrary to the title, this is NOT a Free-Add-Comic. You are free to edit the page and/or add to the story, but do not be surprised if your edits end up reverted.
Seriously, this is super contradictory. Why make a COMMUNITY comic when you're not even gonna allow the other kids to join?
Here's one of my favorites:

Someone tried to pull Animator320, who was confirmed to be a pedophile after they made NSFW of some of their characters (who were fucking toddlers) into one of the chapters for god knows what reason.
