I do also think, could be wrong, that people are listing over priced guns on here. Then going to create a new account and saying I will take to make it look like people are buying these insane prices. Might just be me though.
TacticalMountaineer, It's my suspicion that individuals may also be creating dummy accounts to pad their positive feedback scores. Heck there is probably a whole host of angles people are using to dupe people. I guess there are always a few bad apples, right?
One thing the postoffice does to ensure that you are who you say you are during change of address is get a credit card and bill a dollar from it to verify name and address. Probably too many parinoid people in ODT land that would be against this but in lieu of honesty and integrity it might solve some problems that occur.
