We got banned from PayPal after 12 years of business
PayPal suspended my account once when I paid $5 to the NoScript guy.  I called, they wouldn't tell me why they suspended my account because "that would allow people to get around the rules", and they gave me zero warning in email or anything.  Next time I went to use the account, it was frozen.<p>I don't remember how/why/when it was unsuspended, or maybe I just opened a new one.<p>Not telling people what rules they supposedly broke is unreasonable, even if it lets bad guys figure out how to get around them.
