[Suggestion] Add a pinned thread with tips to the trading section [no GA]

I know that the site is mainly aimed at giveaways and less at trading but since there is no support for the trading section wouldn't at least a thread with tips for new users be useful?
Lately there have been many successful impersonations and a lot of new users have lost their games. Most of them have never heard of impersonating before and don't know how to protect themselves and act in such cases.
I think a couple of useful tips and tricks would prevent a lot of scams.
A quote from reddit's game swap page (something like this would be fitting) :
"Protect yourself!! Do NOT accept a trade if someone adds you on steam or sends you a Private Message (PM) without commenting on your thread first. These are almost always scams. 90% of scams that occur are because new users accept random invites from scammers. Banned users still have the ability to PM and add you, and they use this method to scam new users."

Edit: Also 95% of the people using the site for trading have never read the guidelines so a adding them to a pinned thread would also be helpful.
