In order to inform people about scammers, uap sellers, what's happening on jsp, Why don't the mods create a sticky thread on each East trading forum and mediators/Trade assistant could post in order to keep the gossip up to inform people?

Or even to inform people the new rules, the minor changes, etc.

Wouldn't that be a great idea?

There's a very interesting area of the site titled "Scammer Accusations" that does a great job of handling scammers and UAP sellers.

To advertise cases on suspicion when they aren't proven is dumb. What if I got really mad cuz some user backed out of a trade, so I just posted on the "newspapers" that he sold me unperm as perm to tarnish his rep?

No.

It would be abused

Only if I get it delivered to my door once a month. Otherwise this is a stupid idea that deserves a no.
