"Diaspora's account was frozen for a short while by the eBay-owned payments biz, without explanation"
Thats no surprise, paypal froze an account of mine with no explanation years ago, only a few quid in it so not really that bothered. The account is still alive though as i can login just it won't let me do anything while im there. I can't even close the account without resolving the issue. Which when i telephoned paypal to ask what it was they person on the phone didn't know and told me they would get me a call back from a supervisor which i never received.
