in the cases where they are persistant, i love to start messing with them "oh sure can you repeat the location?" stuff like that. i don't do this with people i believe to be genuine but scams get the full force of stringing them along. after all, the longer they spend time on me, the less they spend time on people who may not realize its a scam
Oh that's a good idea! "the longer on me, the less on others." You are selfless. :)
