google has stopped new account creation because they reached the actual users limit.. aaaaaaaaaand, who can say that u keep the BTC and no invite at all? =P u was a newbie till yesterday and using a mailinator address (ok is for spam, but.. i cant trust u sorry)
The regular way you invite people has stopped, but you can still invite people individually if you have their gmail address. mailinator is for people that don't feel like using PM (or can't, I think there's some restriction on it) and don't want to publicly post their email address.
Of course there has to be trust at some level. Make you a deal, I'll send you an invite if you'll then send me the .1BTC? Need your gmail though.
