Do Not Feed the Trolls
Apart from that, the most important advice we can give is whatever you do, don't feed the trolls. Trolls thrive on getting a rise out of people, and if you reply to their comments, you're just giving them the attention they so desperately crave. And, if you respond in a negative tone, you end up becoming just as bad as them and fan the flame war, so to speak. Be sure that you're setting a good example and adhering to the best netiquette practices.
Our most important suggestion: The best thing you can do is learn to deal with, and when necessary, entirely ignore the trolls. Unfortunately, it's something we all have to do, both in real life and on the internet, and while there are certain tools to help you avoid them completely (depending on the site), no solution is sweeping and foolproof, so the best way to get past it is to hold your head high and power through.
