A Title Much Cooler Than Anything on the Old Site
You are correct; the ban/policy implementation occurred in the public gamers-wanted posting service.
Well, then they are free to set the rules for that service. Players have other forums where they can seek other gamers.
Allowing girls-only game but not allowing any other exclusionary games is common, and I understand the reasons for this, but it is getting more complex. There is an ugly history of first-generation feminists discriminating against transsexuals. I think that it would be easiest to simply not allow the posting of any game that excludes anyone for any reason other than limiting to or excluding children.
