I will completely abide by any decision that is handed down by the mods here. Them's the rules, and that's that.
However - and not that this matters, but I just wanted to put my opinion in - I can't completely agree with this decision.
Many (most?) of us come into contact with people who repeatedly run rampant over etiquette. And not the "the shrimp fork is the X one on the left" kind of etiquette, the "You're a fellow human being and I'm going to show respect for you" type. The normal human reaction to this kind of treatment is anger, shock, et cetera. And most people need a way to get that out.
The benefits of ranting about etiquette violations here is that it often opens up a discussion - how it could have been more politely handled, what the best way to defend yourself is, et cetera.
I agree that to be overwhelmed by nothing but rants would be bad for the board; but there's got to be a middle ground between letting the ranting overtake the board and putting an edict down that anyone who rants immediately gets a week-long gag.
Maybe modly PMs to individuals who are ranting too much and asking them to take it down a notch, and/or general "OK, guys, let's tone it down" notices to the board in general?
Just my two cents.
