I would find it beneficial to add a search bar to the SA forum, therefore you can see if people you are trading with/accepting into a guild have been accused of a Scam before. Even if the accusation was a fake accusation from someone with a grudge it would still be a useful feature to add.

What say ye?

Obvious yes, so if you think someone is sketchy in a trade, it'll take 5 seconds to see if they've been recently accused.

definitely got my Yes

This will only facilitate people opening false accusations with the sole intent of defamation of character, which of course will have another adverse affect of pulling the SA staff off other LEGIT accusations. No thanks!

Use a mediator.
