Well, technically you could write a chrome extension and leave the extension and computer running over night...and automate the clicks to block the user once it appears again.
I did something like this in the past but facebook updated their design so my extension meanwhile is useless. A former friend of mine's account got compromised and was spamming me (via email) every time their account was online. This was the only way to get rid of it.
