When receiving money can the person who sent it deny, block, or otherwise recall the money once it is sent? I recently got burned in such a manner on another platform where they sent the money and I withdrew the payment but they stopped the payment a day later on their end which I then had to pay back to my bank.
That depends on many factors all listed in Paypals seller protection policy for you to read so you can risk assess your transactions. Legal (bottom right of Paypals pages) > user agreement > seller protection.
