A topic could and should never be bumped when you are replying your own topic. It should only be bumped if another person is posting something.
If bumps are intended and allowed there should be a bump button, but it should not add a noisy "bump" message for the last 10 pages.
Hard to keep track of what is being said / bid and would prevent people from doing +1 bumps.
Just my thoughts on bumps lol
