If a post is deleted for certain content..

And access to general discussion is disabled, how or when is that block removed?
I had this happen for reasons I'm confused about. But, is this block permanent?

1. You don't get blocked from a forum for having a post removed

But you will get blocked from the thread where you had the post removed — you won’t be able to post in that thread again (unless you appeal and your appeal is approved).

2. After that notice was sent to me I've been unable to enter 'general discussion'

Not only that particular thread, but even to begin a 'new discussion.'
Is that temporary?

3. When you say "unable" what do you mean?

What exactly happens when you try to enter the forum?

4. I was unable to post on 'general discussion' for about an hour, but now can....

Thanks for replying..
it must have been a temporary block.

5. We do not temporarily block people from entering forums if they have a post removed

Perhaps you were getting a "403" error? If so that is a temporary glitch which usually fixes itself fairly quickly, but it's got nothing to do with post removals. It's hard to know without the details -- but I'm glad to hear that whatever it was, it appears to have resolved itself.
