How do i block an IP address

[FilthyBella]

Hi all,

Just wondering - is there a way that I can block all views from one IP address.

This is the story.....
So I have a male house mate and I know that he has been viewing me - I viewed his cam. NOw obviously this has made things extremely awkward between us as he is a bit of a weird one. Anyway, I think he changes his username each time from what i can gather so im trying to figure out a way of blocking him totally but the problem is we all share the internet so im guessing we probably have the same IP address.......

please help a distressed Bella.
