Is there any mechanism where I can ignore absolutely everything from a specific user?
(Yes, this question has been asked before, without any public answer, back in '08. That's not just thread necromancy--the software has changed.)
I already ignore their posts, but I still see threads originated by user. I want my page to be entirely free from any content originated or referring to the individual, forever.
A disclaimer: In fairness to the individual in question, the user doesn't post off-topic material, offensive language, or is any way hostile. I have simply never seen any value whatsoever in the user's posts or the discussion following one of their threads. I'd rather see half-page ads for sketchy cryptocurrencies using both flash animation and the blink tag than content from this user. YMMV
