I don't believe in using the Ignore feature. Not unless someone is flat out stalking me. And I doubt that this forum would put up with such stalking as I have seen elsewhere (thank God).
For me, the ignore feature is best for flow of conversation, and seeing only actual thoughts from posters, either pro or con.
Right now there are only two who just cannot do that; who have absolutely nothing to say that is not snarky, evasive, or downright mean.
But, I have been stalked by one whom I have on Ignore, and putting her on ignore stopped it. You'll have to see how it goes and you may find it best to do the same, even if only temporarily.
As for the forum, the big difference......... no, HUGE difference.......... here is that bad behavior is always frowned on. Rather than sanctioning the Trump bullying as happens on TOS, here it is strongly discouraged.
