It sounds like someone is harassing you: I recommend sending an email to staff using Special:Contact, giving a link to the user's profile and explaining your situation calmly and clearly.

-- if he's using different IP addresses, you can do a range block (if you've observed that all the IPs he's using are in the same range). But if the IP addresses are random, then no, there's nothing you can really do.
