The Don't listen to Wayne Kerr aka Mama Kd. It's rude, insensitive and misogynistic males like that female rooms don't need.
Males are going to go to Lesbian Chat, Girls Chat and where ever girls are, period and there's nothing that can be done about it. Some go there and are sincere in just wanting conversation or a different point of view. But, yes, there are those that go there to cause trouble, degrade and insult females. Either way, Ignore and Report are your best friends. It's pointless to report someone in the room just because they are male as that will ultimately only get you in trouble for false reporting. Put males on Ignore if that's what you feel you need to do and chat in the main or create a side room for females only, that's about all you can do. It's not going to change.
The males who go into girls chat and lesbians chat are the ones who can't get a female in the real world. For whatever reason they get it stuck in their head that if they go to a room where there are females where they know they are not wanted in the first place it may work for them.
