We don't have any way of blocking buyers by IP, as that's quite futile and more likely to block legitimate buyers than fraudsters, who already quite commonly change their IP address with every attempt, simply by resetting their router or visiting different public wifi hotspots; if they're sharp enough to use different emails, they're almost certainly already using different IPs as well. Blocking an IP they've already used would simply block everyone else who happens to use that hotspot in the future, or who happens to get randomly assigned that IP by their ISP the next time they connect.

Send an email to support with that IP, and we'll see if Development can manually add that IP to a temporary block list:

We don't normally make IP blocks available to sellers directly, as aside from the general futility of it explained above, there's just so much general misunderstanding about what IPs actually are and how they work, that too many sellers would wind up effectively shooting themselves in the foot by playing IP whack-a-mole (if you'll pardon the mixed metaphor), and then it would become difficult to troubleshoot cases when a legitimate buyer has been shut out by one of these blocks.
