Love the poll!!
For my own self, I've found that Ignore can have different functions. I can only remember putting 3 people on Ignore.
I've been on CC for 17 years, and early on, there was a man who said he was married but having problems. He also stated in one of the threads that he was interested in me. I don't know if he was trying to test the waters -- way back then PM (private messaging) was free -- but thankfully he didn't try to PM me and announced it publicly instead.
I put him on Ignore.
I thought about it a while, then changed my mind. This was the beginning of how I learned to deal with trolls and antagonists over the years -- I write threads about what they say. So I took this guy off Ignore and wrote a thread asking what other singles do when married people try to hit on them.
The thread didn't name him or call him out specifically. Most people were oblivious to what was going on and answered it like any other thread, but this guy was hopping mad and obviously got the point. He soon left the site -- though anyone can come back under another name.
The second person I put on Ignore was someone who had a mad obsessive crush on someone here and would get upset and stir up trouble any time they thought someone else was trying to talk to their crush. I put them on Ignoe because they would try to ask me if I had seen their object of obsession talking to anyone else.
I can't remember who the other person was or why, but I do remember putting a third person on Ignore.
All of these things happened many years ago.
Back then, we had a very regular crowd in Singles and one guy said he had over 60+ on Ignore.
The thing is, it's very amusing to watch people try to keep up with conversations when they put the big talkers on Ignore. It's like wearing hearing aids in a crowd and still trying to participate in every facet of the conversation.
I've seen other people attempt to do this when they author threads. They can't see exactly what's going on, but they interject with their own strong opinions anyway. There was one thread where a long-standing member and I were exchanging ideas in a thread and the author came in and yelled at him because he had me on Ignore and couldn't really see what we were talking about. He mistakenly thought my friend was talking about something completely unrelated.
So basically... You might not want to write threads if you have a lot of people on Ignore, because it will most likely make you sound like a moron.
Me? I'm enough of a moron even WITHOUT having people on Ignore, so I don't use it because I've found it's easier to skim and at least figure out what's going on if I want to be part of the conversation, but that's just me.
And I don't mind if anyone puts me on Ignore.
In fact, with many users in the past, I've asked them too, because, for the reasons I've already stated, I don't put them on Ignore.
And for some of the really, really... interesting... members we've had here over the years...
Having them LOUDLY declare they're putting you on Ignore -- only to then answer you in the next post you write

(which I've had happen several times) -- is really a badge of honor.
