I remember getting inspired by the "Polandball" comics, so I drew one myself. Even followed all the stylistic rules laid out on the sub and everything. But instead of just being allowed to post it you have to submit it to a mod first. And the mod rejected it because he didn't get the joke. So explained the joke to them but they still thought it didn't make sense, so I didn't get a licence to post in the end.
I understand that there are rules for the kind of stuff you want to allow but come on man...
