So pretty simple,
I see a lot of trusted/mediator tagged people viewing spam threads and not closing them. Why you might ask? Because they do not have the right, only Trade Assistant or higher can close a thread. My suggestion would be that anyone who is trusted/mediator tagged could close threads.

I've often wondered why they don't already have it, it's a great way to cut down on spam

[x] Yes

the trusted/mediator status is only the first step towards a position where one can be trusted with such rights

we have the groups system in place for a reason

sorry, but this won't happen so I'm closing here
