infraction question

Wtf? I got a gravedigging infraction from TDD when they're way worse problems with the P-server section then just gravedigging. I don't even know what gravedigging is. Is it just finding old topics and posting about them? How is this against the rules? I understand that this is one of the rules, but why?

There's the link.

 

wow, why even bother disputing it 4 days after it expired? GraveDigging is when you post in an ancient topic which pushes it to the top of the forum, which is useless, so it's against the rules.

 

I know it is expired, but I didn't receive a e-mail, and I just saw it on my CP.

How is it bad to gravedig? It kept the topic alive, and probably helped them out.

 

If it's expired, there's really nothing to dispute.
