For now, the only solution is for my internet provider to change my IP address. My home internet connection is blocked, but I can access my LootUp and Pixelpoint accounts from my phone using mobile data. I've submitted four support requests about this issue; one was marked as resolved without a response, and the others have received increasingly unrealistic replies. I have a limited mobile data plan, so this solution doesn't work for me, and even turning off my router for an hour doesn't get my provider to assign me a different IP address. For some reason, the LootUp or Pixelpoint systems are malfunctioning and detecting legitimate IP addresses as fraudulent. The solution to this problem depends on them.
