Sorry, you can't prevent a single user from viewing your posts. If they are specifically targeting you for any reason, let a mod know (providing examples) and it will be looked at. If it is simply a difference of opinion over something, there's not much we can do I'm afraid.

How do you prevent a specific user from seeing any of your posts? I have tried adding him to the foe list but it doesn't work. The user has been on my nerves and I don't want to deal with it anymore! Thanks for the help!
