Well, I'm sorry, but that is just the way it is. If everybody bumps threads, then there is no point in bumping the thread because it wont be on the top anyways because other bumped threads will be on top.
Furthermore, this rule implies to 90% of all the forums on the internet, so it isn't something "we" invented.
Bumping threads/double posting is considered spam in most cases... These are the rules, I'm sorry if you don't agree with them. But if you want to visit this forum, you must try to stick to these rules...
btw: another rule is not to go off-topic in a thread.. Because we all did this (we are discussing a subject which isn't the threads subject) this thread will be splitted. You'll see... and that's also not a dumb rule, it's to keep threads clean and on topic and to not make the forum one big mess
