PayPal belongs to the online auction house itself and remains the best way to pay for something that has been earned on ebay. It is a third-party service that deals specifically with sending and receiving funds and has put in place a certain level of security. As an intermediary between sellers and buyers, payment details are kept private, electronically and securely. PayPal also has a number of other features that improve its security, including buyer protection, which is offered, for example, during qualified eBay purchases. Reason: Lvis stands for Licensing Verification and Information System and “Lvis validation blocked” may occur if an offer is contrary to the eBay offer policy. It is very likely that your entry contains blocked words, hyperlinks or your sales limits have been reached.
