We played like that for over a year and I don't understand how a user at the time should know about a rule being changed if it only gets announced in the staff discord channel. As long as its not public we should not punish users for something they can't even know about.

For a rule to be changed it needs to go through proper channels which it did not until after I was punished for it and DEAD had to intervene. Meaning it was not a rule, but a rule suggestion back then and a suggestion had no place in the announcement channel in the first place.
