plz note, I had an idea

How about instead of having "later" and "unread" (or keep those and add a function) and WITHOUT ADDING KILLFILES FOR USERNAMES, let a logged in user select certain threads which NO LONGER SHOW UP on the screen? Just pass through threads and when you see one that is likely to piss you off, go to it and MAKE IT DISAPPEAR FOREVER from yr ILX experience by clicking on a link right there after the "Ask A Question" link.

Since people have so much trouble ignoring threads on their own, and killfiles would be ineffective. It seems it would be trivial to store 'dead threads' on the user cookies, and it could certainly go a long way to reducing troll presence for most users.

I should post this to the Mod Req forum eh.
