Danng, you seriously don't deserve to be trolled. You could try telling them to stop (though they might not agree to your terms). You should make sure you're right before reporting them, or send a message to an admin concerning your suspisions.
Ugh, trollers are so annoying.
The whole point of a troll trolling, is to make the other person mad, i dont think telling them to stop is going to do much, if anything make him do more..
