It should not be assumed that all active members are following this thread.
There is not much we can do about that, aside from starting a banner campaign "advertising" the new rules. And even then, some people won't read them.
I'm going to update the "rules" sticky topic in GCC once I have the new guidelines finalized. The title will reflect the date of the last change.
At that point, I consider it to be the responsibility of the users to spend a few minutes and familiarize themselves with the updated guidelines.
Most probably won't do it. And they will get their posts deleted eventually, which will "force" them to actually read the rules.
This is how I think it's going to happen.
