So I'm trying to submit a new tab but I keep getting an error "Sorry you cannot post a link to that host." when creating the topic. This hasn't been a problem before (there's the Eau de Vie tab from me for example and that worked just fine). I even somehow managed to delete my other submission topic (Castlevania tab) while it all happened (and now, I can't link those tabs either anymore, even though they worked before).
What's going on here?
EDIT: Looks like I've gotten messages saying my posts have been hidden because they've been flagged as spam(?). Why did that happen?
