It has many security features to insure you get credit for what you trade in, including an active administration who refund credits really quickly (like within an hour) if you file a report with evidence.
Just, for the love of god, check your safety word. Since you are basically giving your items to a stranger and the safety word is the main method to determine whether or not is is one of the true bots, and not just a scammer. There are other methods as well.
Also, see above comment on overpricing. I found that the key price is very accurate, about 2.5 refined for a key. although when it comes to buying vs selling (and you have to do both in order to use the warehouse fully) that 10% cut is what hurts you.
What BMOC conspiracy? Is there no pricing guide untainted by scandal?
