PayPal may limit an account in order to protect against potential risks and fraudulent activities. This could include suspicious activity on the account, such as an unusually high number of transactions, sending or receiving payments from certain countries, not having enough information to verify the user’s identity, or the account being linked to another account that has had activity deemed suspicious. PayPal may also limit an account due to a violation of its Acceptable Use Policy, which prohibits activities that are illegal or involve high-risk financial products.
