@firefly,
Click on the user name at the start of the post - right there on top. This will bring you to the profile. You can peruse, and ignore, or decide not to. It is rescindable.
I've gotten, over time, the number of those I ignore to very few.
Suddenly the number is going up again.
Some folks never ignore, and I've no argument with that.
I get reasons for not ignoring, and I go back and forth on that, and that is literally possible. A thread can look like a different conversation, one way or the other, and you can just do that, see what it looks like either way.
