I just delete or block any incoming correspondence on Grindr.

I did have a dialogue with one remarkably cure looking lad on Vivastreet ads. Most of them are so rough, I can't imagine any one would be interested, but this one looked like a superstar.

I was a little cautious when noticing he had some high security encrypted Swiss e-mail address. When he said we could only do out calls at a local hotel he had an "arrangement" with, but they had to be paid by bank transfer, then it is was an obvious scam.
