@edgarblythe,
Anyway, as for who'll "admit to ignoring one or more members" -- admit? Is it supposed to be something embarrasing? -- sure. It's a useful feature, I use it.
People have complained for years about scrolling past the stuff of those who really are just trolling or incomprehensible. And complaining about all the people who will reward those trolls by massively replying to him to tell him how stupid he is. Rightly so. Well, now there's a solution.
Press ignore for the worst posters, and no longer do you need to scroll past their endless copy/pastes, no longer do you need to read really offensive stuff that, no matter how much you tell yourself "oh it's just poster X", eventually ends up riling you up, no longer are you tempted to respond in-depth to fact-check each inane bait, losing hours in the process with zilch result. I love it. Putting as few as just half a dozen people on ignore already is like, Ooooomm, the skies clear and suddenly a2k is a site where reasonable people discuss their disagreements, rather than a pigsty where you have to scroll past endless baiting and ranting.
Of course, I post or read a lot on Politics, so that makes a big difference. If you mostly post on Pets & Gardening, I'd guess you'd never need the function.
None of this, by the way, has anything to do with silencing dissenting opinions, or as one poster here said, making a2k a place where you only ever meet people who agree with you, how boring. I doubt anyone uses it like that.
Anyway, currently I've got no fewer than 13 people on ignore. The number is a little inflated, because I've been tagging a lot of old threads and occasionally came across someone that I really never again needed to see a post of again and clicked ignore for, even though, I dunno I didnt check, maybe they arent even posting here anymore. Like that guy who only ever posted about how white people are attacked by blacks and should band together and stand up against black people.
One on the list is an exception; I'm sure I'll un-ignore that one soon enough. It's just the current mission this one's on makes for very tiring discussions that I'm nevertheless sorely tempted to get involved in. So I give my strained capacity of self-restraint a hand by just not coming across those posts for a bit. Function's very useful for that too. I admire those who have an unlimited capacity for self-restraint and can stay out of arguments they know ahead wont yield anything, but I can use the help.
The others are overwhelmingly the usual suspects. A couple of trolls, one or two probably well-meaning posters whose endless ramblings are just incoherent to the point of unintelligible; one or two extremists whose views are just unpalatable (like that white power guy); the odd exception who is intelligent but tends to respond with such personal nastiness that I'd rather not be confronted with it; one who only ever obsessively posts on one subject; (it's the Jews' fault!). Well, you get the drift.
