I send providers a note about there photos on TER , it may say nice photo, thanks for sharing.  
Or if I see a thread and I can tell they are hurting . A nice word to pick them up.  
But what is considered a troll ?  
I do not want to become one! Or think I am freak or something.  
Thanks

A troll is in the eyes of the beholder.  But to me, it is someone who is deliberately setting out to waste a providers' time for free.
There's a thread over on the Newbie Board right now about time-wasters.  Can you guess who started it? LOL!  

All that Debra said and I also consider a hobbyist or provider regularly throwing stuff on the boards solely to stir the pot  with no other contribution a troll. Some folks on both ends of this industry make dubious claims seemingly aimed at gloating or policy reform. PM's can be great, but a hurting hooker can't pay the water bill with them.

If so, it requires one of these.

bad form to PM about photos unless it's in conjunction with requesting an appointment.  These are not civvie women, so small talk is an intrusion into their time.  I agree that if they want to waste their own time, its on them, but they shouldn't waste a provider's.  When you are a regular, many providers will not object to some contact in between appointments, but until you have that status, the OP was correct in his feeling that he might be crossing over to troll-land.  Acknowledgment of the problem is the first step to recovery, so kudos to him.  Lol

the way some guys will purposely "bait" you into responding socially by throwing you a compliment.  Then the back and forth starts until you get tired of it and stop responding.  Then they are off to the next one.  That is classic trolling.  

*bah-dum-dum-tish*

That's the standard forum definition.  Not just on this forum but every forum on every topic in the world.  Some people like to incite drama.  The standard refrain is "Don't feed the troll" meaning don't respond at all, it'll just encourage them.

It could scare off alot of potential providers.
