I have used Tineye in the past - seems to cast a wide net and lets me ask in a followon text (after my usual hi, interested etc txt), if the SP knows the photo advertised as her is on the net as xyz. More than 50% don't reply but now and then if there is a command of English, I get a 'yes ... busted ... but I am not too different" and from there the discussion is real. And for what its worth, some of those interactions are really hot. Maybe because there is some honesty in what is going on. Not sure just that the passion level is up a couple notches.
Also, thanks much to the brotherhood for outing the outright scammers and nasties. Very helpful.
