Troll! Ahhhhh, it’s a troll!
When I find that more often than not I reflexively skip over a poster’s posts even before I confirm that they are as annoying, smarmy, or insipid as usual for them, that’s when I put 'em on ignore.
Annoying annoying annoying, annoying. Annoying annoying annoying, annoying, annoying annoying! Annoying annoying.*
*Annoying
Repetitive?
Annoying?
I was gonna riff with the “prolific” thing but I figured if I did, someone would probably hit me.

I have IIRC three posters Ignored. I rarely if ever feel tempted on those rare instances when they post to a thread in which I’m interested to click to read their posts. I recently did click on such a post and was reminded by the loathesomeness of the post exactly why the person is Ignored.

And annoying.
On edit: OK, I guess I’m the official dork of this thread.
I can’t say I’m surprised people use the site’s ignore function, it’s just that I can’t see myself doing it, only because I don’t get easily annoyed, offended or even worked up about much around here. In fact, sometimes, I’ll admit, certain users kind of break up the monotony around here. Even if I can’t stand what a certain poster might say most of the time, I like to see the stoopid, rather than ignore it.
Is that why I like pointing and laughing at a lot of stuff?
ETA: Linty, I’m glad you stepped up… I didn’t want to sprain my copy/paste fingers. Applause
Heh. 
Aw, don’t sell yourself short, you’re the official dork of a lot of threads!
I put myself on ignore. I have no idea what I’m saying right now.
I use the list, but the majority of the posters on it are banned (either due to trolling or being a jerk).
I did for a while, because that Doper pissed me off so bad I couldn’t see straight…but now, eh.
What Cervaise said.
Usually what happens is I’ll read a post by someone, get irritated by it, and think, “You know, the majority of posts I read by this person irritate me.” Boom, ignore list. But there has to be a history of being rubbed the wrong way by them.
I figure if anyone on my ignore list says something interesting, they’ll be quoted by someone else. I’ve never felt like I missed out on anything by having posters ignored. To the contrary, I feel my time here has been a little more satisfying because of it.
I never have, but I considered it for one poster because I found them so very irritating. (Haven’t seen them in a while now.)
So, what does it look like if someone you’re ignoring makes a post? Can you tell they have posted, but you have to click something to read what they wrote? If they’re the OP of a thread, do you just see a blank OP?
You see a narrow vertical bar containing the text, "This message is hidden because <user name> is on your ignore list. " The timestamp is there, as usual. In post preview, you get, “This user is on your Ignore List.”
On the right side, where the join date/post count would be, there is a link to view the post, in case you want to. There is also a link to remove that user from your ignore list.
Seems like there’s always people curious about this. Test it out. It’s not like you can’t remove people from your ignore list.
:Sniff: Thanks, man!!
Also, the mouseover doesn’t work if an OP is started by someone on your ignore list.
