cash only
Using any third party processor or your bank,
you are very open to losing their service
problem is people (young idiots usually)
will just contact the processor or bank
and they make a fraud claim in an attempt for them to scam you
(most likely it would also be for a petty amount from a petty buyer)
once a report is made your account is automatically frozen/limited etc.
even taking their ID cannot prevent this,
you may be able to get account reopened
but thats always a maybe.
But you can decide before trading with them by taking their ID along with proof that the account is theirs. This way can prevent a possible reversal. Alot of buyers at LBC does it that way. But its such a long a process, and who want's to go through all that?
