A guy stalks me in Facebook?

[Megan]

I've met this man only 2 times in my life - we used to have a few friend in common and all of us went to some parties together. A few weeks ago he added me on Facebook, and I added him back. Ever since all he does is sharing my photos and liking everything that I post. His entire wall is filled with my shared photos and occasionally random football comments. I asked him a dozen times to stop sharing my photos, since they're mine and I don't want them anywhere else... But all he replies is that I'm too beautiful and everyone should see them. So naturally I got annoyed and removed him from my friends list. He then added me back. I rejected his request, then he added me once more, so I blocked him. After that he made a second account, and added me again. Blocked this account too, but he keeps making new accounts and sending friends requests. I reported all of them of course, but it's no use, since he just keeps making new profiles. I just blocked his 5th one. He clearly wouldn't get the "hint", but now all of this gives me the creeps. I don't think he's crazy enough to stalk me outside Facebook... But I'm still a bit worried. What should I do?
