I wouldn't credit them with that much intelligence. When trolls flock, they are no different to sheep; they take the easy option, currently, that's you; they can find you, and you rise to the bait.
If you fell off the radar, they'd probably pick on someone else; and if there was no obvious candidate, they'd probably split up next time they get bounced off a forum.
I think you might usefully 'get in the mind set' of moderators; most simply want a quiet life. If they spot trouble, they just as likely evict all as none, but few will discriminate, and very, very few care 'who started it' (why would they?).
Sadly, but understandably, your warnings of hell to come will never help; they don't know you, they have no way of knowing if you are really a victim - or merely the leader of the flock, about to disrupt their forum!
Even here, where I am fully aware of the scenario you describe, my view - indeed, my rule - is that I'll take all members on their merits - I would never ban someone 'said to be' a troll; I don't think that's fair. I ban on merit; so a careful troll could survive here for a while, while a previously good member who lost their cool at a careful troll would have to go!
My rules are clear, and they apply equally to all; no-one is a troll to me, until they act like one, here, in my forums!
Which is exactly I why I always preach '
don't feed the trolls' - not only does it encourage them (never a good idea!), it means that the troll-feeder may leave before the troll does.
The point of all this, is that for a moderator, no member is bigger than the forum, no member is automatically right, and rules must be applied equally (or the forum dies). It doesn't take a terribly intelligent troll to learn this; ultimately, their nature will come out - because that's who they are - but some are quite capable of being smarmy toe rags while they set out to rile the regulars. A very old trick.
So don't fall for it
