As for safely trading your account, look for someone that meets several/all of the criteria below (in no particular order):
•Someone trusted -- Trusted people usually have a title of
"Moderator" or
"Admin" (you can click either of those to see great examples of someone who is trusted on Sythe. Now, I say
usually because there are plenty of people who do not have a title, like
-R-I-C-H- or
rsaccounttrader just to name a few. What they both have though is the title of a Donator. Donators (usually from upwards of $50+) tend to be trusted because they have given money to Sythe, which not many people have done.
•Old join date -- accounts made within a month or two may try to scam you. That's not to say everyone with a May/June join date are scammers. Some scammers are just looking to make a few bucks and will do anything to achieve that. People with an older join date usually have far more on the line and would not risk scamming.
•Vouches -- Obviously vouches play a major role in trades. The more vouches you have, the more trusted you are. This is not the case for someone who has plenty of vouches, but a majority of them are not worthful vouches like Sales vouches are (this includes but is not limited to vouches from account trades, rsgp trades, upgrade trades, non-virtual item trades, middleman trades, etc). Vouches for "tutorial completion" or "item lending" (etc) are considered worthless vouches.
I might have missed a category or two, but be safe when trading your account and choose someone who you are comfortable with.
