Account trading?

Hello again!

Seems like I posted in the wrong section, sorry about that. So I'm new here, I googled for a site to sell RS accounts. In the thread I saw people recommending this place over those other sites, but they said to look out for scammers. But what should I look out for exactly when I'm planing to sell an account, can I be scammed when I'd sell my account using paypal?
-Thanks in advance

 

it's possible the buyer off your account can charge back paypal, so make sure they're trusted, or that they'll pay gold so you can sell that gold to someone trusted! always use a middleman if you're dealing with people on sythe.

 

Middleman? I thought you sell directly to people around here, okay so how does this work exactly? Also, how do I know if someone is trusted, they have tags with their username or something?
