This is their email to me when I asked them
"
Thank you for contacting PayPal via Facebook. If you did not initiate this contact, please let us know immediately by replying to this email.
I understand that you are concerned about missing funds. From reviewing your account, it appears that your balance was deducted from due to violations of our Acceptable Use Policy.
If you violate the Acceptable Use Policy, we may hold your funds up to 180 Days, may debit your PayPal account up to $2,500.00 USD for each such violation and may take legal action against you to recover additional losses we incur.
When you accepted the PayPal User Agreement you agreed that $2,500.00 USD per AUP violation is a reasonable minimum estimate of PayPal's actual damages, considering all currently existing circumstances, including the relationship of the sum to the range of harm to PayPal that reasonably could be anticipated because, due to the nature of the violations of the Acceptable Use Policy, actual damages would be impractical or extremely difficult to calculate . PayPal may deduct such damages directly from any existing PayPal balance in any PayPal Account you created, own and or control.
The amounts deducted are the following:
$13.60 USD
P2,132.50 PHP
£2,002.64 GBP"
