Basically, its for the Trading section as recently, I make a new topic per day with my offer lists and ive been getting pms on items what i stopped selling days and days ago.. or what have already been sold.

A button or something to get your topic closed... there are three options i can think of at the moment.

Close Topic Button (Everyone can close there OWN topic)
Request Closure Button (a mod will then close if appropriate)
Request Topic Closure Option when clicking Report.

How would this get abused? I don't really understand the issue with it...

id have to agree closing ur own topic seems hard to abuse... what r u gonna close a whole bunch of them? who fuckin cares they r ur threads

People are still going to ask you...
