Unfortunately you still get the [flag] abuse. It seems that some members are able to flag posts and you can often find if you say something disagreeable in a thread that every single one of your comments will get flagged regardless of the content of the comment in question. The comments can be well-written, non-confrontational and be a genuine attempt to start a discussion, but they'll get flagged because someone doesn't like what you wrote but (presumably) can't form an argument against it (like Paul Graham said, people only really hate things that could be true).
