We no longer have any affiliated chatrooms since it was causing too many problems. When we had it people wanted it both ways. They wanted to be able to do whatever they wanted since our guidelines weren't exactly implemented there but when they would run into problems there they would come running to staff here to fix the problem, which we didn't have jurisdiction over.
Some people would source there stating they could do it since it wasn't BL, then they would come crying to staff here when they got banned from there. Or others would come to us asking to stop the sourcing when we couldn't. Other times people would post screenshots from there on here, then they would ask us to remove the pic. Too much of a headache for something that didn't really benefit the site.
