Well, more than that, but they let people get away with way too much shit there. In their Off-Topic equivalent, there are rampant numbers of extreme right-wing disingenuous nutjobs that GAF moderation would've banned in an instant, yet Retro moderation just hems and haws about them, maybe doing a three-day ban in an egregious case. On a blue moon. When it's raining. While the sun's out. And there's a double rainbow. Which pigs are flying toward.
As far as the Mania complaints go, they tend to come up with the stupidest shit. People complaining that Tails making a strained face when lifting up Sonic while flying as looking like "a creepy smile", going as far as editing that face onto his standing sprite to prove their point (even though that's not the context the face was made for). People complaining about the plumbing in Flying Battery's background. At least one person complaining that some of the graphics in the game used "MSPaint White" (sorry graphic artists, #FFFFFF is forever verboten). One guy was even adamant that the fact the game was fanmade was inherently a deal-breaker.
I don't know why I still go there. Once upon a time it'd have been because Strife tends to post his Freedom Planet updates in there, but that hasn't been the case in a good while.
