You can go into your profile, then set "showdead" to "yes". Once you look at bellingcat's domain submissions, you'll see they're mostly "dead" and that makes them hidden from unlogged and most logged users, so it's like they're automatically taken out of the pool of articles available to receive votes. Only once someone "vouches" for a dead post can it be voted on again.

Usually posts go dead when downvoted enough, but it seems posts from that domain are automatically set to dead, and a few of them are resurrected.

Btw, the best place to find dead posts is the newest page, as they are uncommon in other places.

Edit: sorry if I sounded condescending, I might have misread that as you not understanding what "dead" meant, rather than "why would that be an issue".
