Dustin, how nice of you to choose me as the example . Or did I just say "Poster banned. unban"?

Sorry, what was that now?

Does this work in practise? What if you have a problem which the banned user answers. Then you write something like "Anyone?" after he has given the answer. It will look strange anyway.

Pretty cool, thanks Dustin!

kentl: Look at the screenshot

Yes I looked at it before I posted. What about it?

It says poster banned when a banned poster posts (man, that sounded like a nursery rhyme or something). So you won't just be oblivious to someone posting. And you can unban them just as easily.

But when would you actually keep someone banned? It could get strange in almost every kind of situation if you miss a post by someone. And if you always have to switch between banned and unbanned it sounds like it will get tedious and more annoying than just skimming through uninteresting posts.

I guess a cooler, but not necessarily any more usable approach would be to show the post as normal, but hide the whole thing with the poster blocked message, then provide a link to view the post anyway (without unblocking them).

Also, block is the correct word here, because you aren't really banning them, just blocking them.

Funny. Allegro.cc is one of the only boards I'm on where I wouldn't even consider blocking someone.

Yes but isn't "banning" someone a tad more satisfying?
