What does it mean when a user has a line through their name

[arcteryx]

I am trying to reach https://forum.ih8mud.com/members/auburnfjsexy.html

But get a message saying they cant receive messages or have chosen not too. Looking at his profile, his handle has a line through it. What does this mean?

Edit- Actually, I see a few people with their names through them This was yesterday/today. https://forum.ih8mud.com/ga-georgia-cruisers/595050-beasley-next-i-think-so.html

It means they have been banned from the forum.
