Ask HN: How do you prefer to anonymously receive money?

In case you run an internet business where you receive payments but want to remain anonymous (therefore your personal Paypal account won't be adequate), what method/services do you use?

(ie: you sell items you'd rather not to be linked to you in any way. ie2: it's a grey area business, such as porn sites).

Please explain your use case (whether you do B2C and/or B2B). Any advice is welcome... Thanks!
