Do you flag threads, posts, comments, etc. often?

When I see a thread that is obviously spam, I do not hesitate to flag it. I get tired of seeing crappy threads filling up the forums asking stupid "questions" or posting things better left in the comments section of the product page like, "How big is this?" or "I like this" (only in horrible English, of course). I'm not quick to flag, however. I don't flag things that don't need to be flagged. But I don't just ignore it if it's a spam thread or the like. This is ESPECIALLY true if they've posted multiple spam threads. My threads may be stupid half the time, too, but that's not because they're spam. I'm just uncreative.

So, are you a flagger? Do you flag some things and not others when they should be? Do you tend to ignore spam and not flag it? What do you do? less
