Well I agree with that completely - I've got past the point where I even read emails from these places before I delete them, and I keep my ads now to the places which work for me so it's easier to keep track. For trans escorts it's different though, because many of the main directories won't take their ads.
Adultwork works wells for some and not others, although I think location is a massive factor here and to give it it's due it's pretty inclusive (because it wants everybody's money, not just people of a particular type/age/gender

). Sites where our ads are mishmashed in together with dating ads just confuse - we've had people here trying to push these sort of sites before and they've never lasted long. The shitty attitude is neither here nor there, but the complete refusal to address fair questions about the site they're trying to plug is, and if they won't do that then there's no point in them being here.
