Use ignore would be a useful solution if it ignored those posts and anyone quoting those people and if people are tagged. Until it has that function it doesn't remedy the problem because you still have a ton of pointless response bloat, but that are out of context, so I've found ignore actually makes the thread slower and worse to navigate overall.
Yes, others have been run out of the thread for being stupid idiots, which partially highlights the problem. The current crop of potardos don't get shamed into leaving by bad arguments because they're not there for discussion, but attention. The worse their argument, the more they post it over and over, the more attention they get, the more they're encouraged to keep posting dumb shit that isn't in good faith.
My solution would be limit people to 4 posts a 24 hour period. That way we can all decide how to use our posts, whether it's 4 novels by Lithose linking the Lewinsky hypocrisy, 4 random tweets, or 4 responses to potatards.
That way no censorship, just limiting the noise and make people think twice about the dumb shit they're about to post.
