Deposits for regular escorts? No way, not ever. Plenty of Fish. For parties, with a organiser that is trusted? Could be a valid choice - not plenty of fish - there are not that many parties. A slight gamble with the cash. But how to minimise a gamble with security?
To do it safely, this route has worked for me: 1) I have a PAYG debit card. Mine is FFREES. Not connected with anything else I do. 2) I have a spare paypal account. So I open paypal, make the transfer (via escorts sort code and acc number), and paypal takes the cash from the PAYG card. Not saying this is fool proof, just saying it has worked for me so far.
