At times bumping can be a fine line too. Someone who "bumps" their post 16 30 and 45 min after their first post is blatantly going against the rules. However, if someone bumps their post with more than a "bump" or "help me now", and rather adds an update or more info, that is ok, or generally, if it's been more than a day and the post still has no responses, and is something more than "look at me," asking again in the thread for assistance is usually fine.
