It's easy: Don't reply. I get that a lot of people, particularly youthful in experience, have impulse-control problems. Yet in my experience, there are only two directions a troll will take a thread on a forum:
- Community-induced Streisand Effect
- Nowhere, because no one gives a crap
From my observations, the trolls in recent months have been particularly happy with the attention they get because the same subset of CDenizens keep replying with accusatory "proof". This effectively validates the existence of the troll. These are (typically, in my experience) the same users who are most likely to de-rail a thread which has tangible information of interest to those of us who actually value our time in the summer.
Thus, the best way to deal with a troll is to let the troll beat its own drum on deaf ears. If we don't pay it any mind, like the tantrum of a toddler, its own irrelevancy will be its undoing. Acknowledgement and attention gives confidence to the troll (or toddler, if you've got one...).
If you'd like to point out that someone is giving a genuine reply to what
you believe is a trolling thread, it's probably best to do so through PM's.
Happy Posting!
Backstabbing your opponents at the last second will not help you win friends and word will get around pretty quick. Your team will be shunned and distrusted for years. People have long memories, and some of us mentors have been playing this game since you kids were playing with blocks. - ChrisH [more]
