User level preference to black-list posts from domains

My question is would it be possible to have a user-level preference to not show posts which link to a certain domain?
I want to clarify, this would only affect the user (based on their preferences) and what they see on tildes.

Asking this question after seeing a bunch of posts from intlnewsdesk.org being posted here, and I am not able to find much about this site and would prefer not to provide more traffic to this site. (Seems like the user posting this signed up a day ago and pretty much has posted only articles to the above mentioned site).
