Many of the above, plus:
*"I'm looking for a lady I can see regularly." In the same vein as "money no object."
*"Just one more thing/another quick question..." If uttered multiple times.
* "What do you do in the hour?" Especially if they've found your ad on something like AW that has a likes list.
*"Can you send me some more photos of yourself?" As if I want to help build up his free private porno collection.
*"Great I'll look forward to seeing you then!" Hasn't yet received an area/landmark/ postcode and showed no sign of asking for one. TW rookie error.
Oh yea, and dick pics. But that's pretty transparent.
