HEY GUYS
If you're receiving LJ notifications for payments that you don't remember making, it looks like it might be a bug/LJ sending old payment confirmations. MAKE SURE YOU CHECK THE DATES OF THE PAYMENT THOUGH I've heard of people getting them from November/December, myself included, but afaik no one's been actually charged for it. BUT JUST TO BE SAFE AND ALL double-check your accounts and whatnot.
Here's a handy
link if you're super freaked out by it and want to let LJ know of their fail.
Editted to make more sense. :|a
