Yeah but subtler mate. Trolls operate in the serious / can't be serious grey space. Calling their bluff will either reveal their insincerity, or if they're good at it, be indistinguishable from actual sincere held opinions or beliefs, in which case they might think they've trolled you, but if you look at it from the other side, I've just had a pleasant experience.
You faked loving me, but I still came ;) Was it good for you too? Then maybe you didn't really fake it.
Of course, don't go slutting around with just any troll, you got to feel some spark!
Seriously though, perversity takes effort, most trolls are too lazy. Call their bluff by taking them seriously at face value, they'll usually fold, or go all in.
