People need to be removed or "put under review" as they say, when they message you for no reason at all other than to waste your time. The internet has spawned a whole generation of total flakes. Not accountable for anything. They play this game where they'll message you then not respond. Then if they do respond, they'll tell you that they weren't aware that they messaged you at all. This happens at least every hour. Then they will ask you more questions than a homicide detective, none of them will simply "read the post" then after a billion questions and commitments to show up, they flake out anyway, then get all but hurt when you call them on it. I learned early on to NEVER GIVE OUT YOUR ADDRESS because 9 times out of 10 their not coming anyway.
And when they really want to play jerkoff games, I cut the price in half, and give them an address across town, then the game is on them. Instead of them wasting your time, you've wasted their time. It's the only way do get satisfaction on these losers.
