Paypal have been known to take the option from those who they deem are abusing the option.
Not saying you're doing this, but do you make lots of paypal gift payments?
Paypal, after all, are only really interested in customers from whom they can get fees from (goods, etc..)
There is a url called paypalsucks as well as another site I can't recall that's documented this.
In the past they've limited my account for all kinds of silly reasons.
