There's this one twit who replies to every one of my messages, directed to him or not, with "wrong" or some such nonesense. I block him, but every time he logs back on I can see him again.
His address looks something like
user####@blah.blah.blah.blah
where user#### is something different each time. When I /ignore him, it only ignores the user#### he's known as at the time. How can I /ignore the @blah.blah.blah.blah portion?
