Enforcing a "Do not post to me" request is understandable if [big IF] the complainant is being harassed by personal attacks.
Enforcing a "Do not post to or about me" request is in most cases giving protection to the controversial views of the complainant.
No disputing what you wrote.
My experience was with a admin/mod on another website that ignored multiple requests to put an end to a particular practice, then eight months latter blaming me for responding ‘in kind’.
Anyway, its not an issue here at FR. And I’ve since realized it was much more about my influence, and being against kooks like Ron Paul or windbags like Tancredo than it was anything else (the site owner is a huge Paulistinian).
The mods always handle personal attacks. Always. I wish I had a dollar for everytime I’ve seen “Don’t make it personal” or “Knock it off”. Most of the time “do not post to me” is little more than a crybaby tactic put into play when someone won’t agree with them or when that person is making a point. It’s much like the MSM behaves when a person is making a point & they’re “out of time”. It shuts the other person down & gives the whining one the last word. It’s not that hard to just ignore someone. That’s what the scroll button is for. And maturity is a plus too.
