I'll assume you are rather

I'll assume you are rather new at this, so excuse me if I come over as captain Obvious.

Just look at who posted the thread and who bumped the thread. If people bump a thread, they will say that they did so most of the time and say "bump". This can be someone else, but can also the thread poster.

Sometimes, a thread poster can bump his own thread without it being obvious. He will merely reply to his own thread, without saying "bump". This will put his thread back on the top page.

Bumping isn't wrong. But doing it excessively can cause iritation. Wouldn't bump (either blatant by saiying "bump" or by doing it stealth as described above) a thread more than 3 times.
