Been playing D2 again lately and see a lot of new users on here and before trading if a user is new or few posts, high warn etc I always check the S.A. forum before making a trade. And while looking through there it occured to me, why cant there be a search bar like in the trade forums where you can type in someones username and see if there are any accusations on them.

I like.

Nope

If you don't feel safe about a trade use a mediator

Been suggested and denied as far as I'm aware

On top of that, if new users are getting scammer, it's not like they're going to know to even check scammer accusations, really.
