How can I block someone's Facebook profile so I can't view it?

Sorry, that's not possible. If you were to block someone's profile, it would mean they would also not be able to view yours. You would be removed from each other's friend lists and won't even be able to search for each other.

The best you can do is to tell yourself not to look at that person's profile (this is tough, I agree). I guess the other option is to hide them from your News Feed so that atleast if they ever put up a new status or pics or something, you won't see it right away. When that person shows up on your News Feed, just hover your mouse over the name until you see the "Hide" link to the right of their name. Click that to hide them from your News Feed. They won't be blocked from seeing your profile, and maybe you'll be less tempted to visit theirs.
