who would be the person to talk to regarding this?

sick of having to deal with one idiot who constantly bumps months old threads and craptalks in everyone else's threads.

Best thing you can do is report it if there are violations and move on. Every report is looked at and dealt with appropriately by the staff members who moderate those sections.

Ye reporting is the only way !

Aside from that just keep a list and submit to the moderator of the forum. Sometimes reporting the mods don’t know what’s fully going on so you need to give them a bit of detail with a pm and evidence.
