Several Hosts have reported that PayPal have added new requirements for identity verification, but have not always advised users. This was mostly Canadian Hosts.
My suggestion is to contact PayPal and even if they say your account is fine, ask them about increased requirements for ID verification for business accounts and/or limits on the amount of funds received.
PayPal has implemented a Customer Identification Process (CIP) that requires users to confirm their identity, including personal information like name, address, and date of birth, and may require uploading documents like a government-issued ID.
