The trading rules state,

- Trades involving real world currency should only be done with PayPal. (You are not permitted to use Moneybookers, Bitcoin, steam wallet codes, gift cards, etc.)
Couple of questions:
What is the rationale behind banning each of the mentioned ways of payment?
What about SEPA Credit Transfer/bank wire (in the EU)? It is not reversible, you can include about 80 characters of information in the payment notes. My bank does not charge me any fees (unlike Paypal), there is a real name attached to it.
