Next to each thread's post, you should see an instance specified in parentheses, such as
(lemmygrad.ml)
. Click that item to list other threads from that host, as well as a sidebar box that says Domain
. Click the "no smoking" type of button to suppress everything that domain produces. I think.
Verify it worked by going to your user's settings menu, click the blocked
tab, then the Domains
link.
