Answer junk mail? Spam e-mail? Pretty much the same thing. BTW, since when would having a few posts on a review board make anyone trustworthy? I know I'm not!
I posted a review of visit...got a couple PMs from guys with literally zero posts and recent join dates...with questions about the lady, site, etc Would you answer those PMs with info? (so far I haven't) dunno--don't trust someone with no history...
Generally if they are asking for specific services that I didn't mention (not that I review a lot-sorry guys I do what I can) I ignore them. If they ask about appearance, conversation, something I don't worry will lead to them being a pushy douchebag if they see the lady then I'll typically respond.
