How does people trust premium sellers for pearls?

There are some premium sellers for pearls and PEN buyers for pearls.How does people trust them ? Are they recording a video while trading this stuff or cant prove that ?

 

As long as there is no way to trade directly between players, don't trust anyone blindly. There will always be people who will try to trick you into getting their stuff with zero investment. If you still insist on trading with others, make sure you have screenshots of the entire conversation with that player. The trade agreement part is the most important, once the player has agreed to trade with you, and you sent him the item he requested, and you didn't receive what you were promised in return, the player will be severely punished.

 

Okay Thanks !

 

There is one safer sollution. Usualy i only accept deals when
1: He gives premium b4 i do something.
2: He gives half of it before and another half after deal is done.
Also as Noyah said be sure to make screenshots.
