Kelda, that's thoughtful of you. But listen to the good news - when we get the rare troll here at BetterMost, it's not much work at all for anybody. Here's what happens:
1) Troll joins BetterMost and posts one yucky post.
2) A sharp-eyed mod deletes the post. Or a sharp-eyed community member reports the post, and then a mod deletes the post. Yucky post is usually not viewable for more than a few minutes.
3) Admin bans troll, so troll is not able to post here anymore.
4) Admin reports troll's actions to troll's internet service provider.
Simple, easy, quick. All of that is just a few clicks on anyone's part. And it's satisfying for the sharp-eyed user, the mod, and the admin to know we really are all in this together and supportive of our little home here.
So feel free to invite everyone on IMDb over here.

To clarify the nature of the current troll attack at IMDb' BbM board, a few people (using multiple identities) bump inane, outdated [Happy Birthday Heath], or highly negative threads [Am I the only gay guy who hates this movie?], then deleted their posts leaving no trace of what they have done behind. Some of the old trolls who post negative rants are still around, but they are amateurs when it comes to this new group.
Sometimes they create an account to post something inane (example: "What did enus mumble at the end?") and when a few people respond the OP is deleted. (A quick check of the post history will almost always reveal that no other posts have been made by that account.) When the OP is deleted, the thread remains with [Post Deleted] as the title. The thread is then bumped several times a day along with about 15 others, crowding out attempts at legitimate discussion. There are about 4 accounts, each using about 4 to 5 names who are doing this.
Occasionally, they have targeted a thread for deletion by reporting it as "pornographic". If enough different people do that, the system will automatically delete the thread, but a change in IMDb's algorhythm also ignores the reports of an account that over reports and ups its quota.
IMDb would have us believe thay once the post is deleted they have no way to track who did this, even though many of us have caught the perps red-handed several times. So what have they done? They have targeted for removal threads that talk about deletions, threads that name the perps, and accounts that have been using bumps to save threads from rolling off the board (why the frequent bumps? Because IMDb changed its rules and decided to make BbM's board a two week board - any post not responded to in two weeks drops off the back end of the board...
