I see, bump other topics so the trolls will get off page 1.
I've hardly ever opened a troll post, but I can certainly start opening and reporting them, especially if they crop up in the middle of the night US time.
If you open an offensive post, click "report" at the top of the post. Then ask that the post be removed. The owner of the site is the only one who is allowed to remove posts and the report will get to him/her.
DO NOT REPLY. Replying is "feeding" the troll and those offensive posts will continue.
You may "bump," which means replying to post below the troll's and then the troll's post will go off page 1.
REPEAT -- DO NOT REPLY TO A TROLL'S POST!
THANKS.
