Personally, I tend to use it when I'm trying to keep personally things anonymous, I don't want something openly coming back to bite me in the rump, or I am trying to say something, but am concerned that I may offend someone and not be able to explain myself well enough to keep from coming off as a jerk instead of just trying to tell it like it is. I'm not one to go out of my way to be overly blunt or malicious, but for example people have asked for opinions of politics, or how they look. I wouldn't just call someone a "lard ass" or something, but I'd say hey, you look to be over weight, but if you're concerned about it, and want to ditch some weight as I personally have, message me for tips and stuff, maybe I could help. Then if they want the advice I message them or leave my user name in a message.
Some people see that as extremely insulting so I don't want that attached to me, just like I don't want people taking this answer the wrong way so I went anon.
I hope this answers your question I wish you good luck in finding an appropriate answer to your question. Cheers.
Maybe some people are just that insecure about voicing how they feel about something. When I am feeling good about myself I am far less likely to go anon. This site does have a lot of sex related topics, and many other topics that could be seen as sexist, or racist. Once they get into the habit of going anon, they my not even think twice about going anon on any question.
Also some people start crap over the dumbest stuff. If they don't like your answer they start trolling you. Some people just start going anon to avoid that happening, or to avoid someone that has been bothering them.
I rarely answer anon, if you don't agree with my thoughts or answer then that's your problem, but I always give my honest to god opinion were it is needed, because you might never know that it was the right thing to change a persons view on something and lead em on the right path.
When I do answer anon then it might be answering a question with a very personal experience which I'd rather keep secret, but still want to help the person with.
I do keep my profile now a secret and don't use my real picture anymore, because of hateful remarks from trolls and idiots.
I do it on every question I answer for the same reasons that peace.love.couture mentioned. At first it was only for the more controversial questions because I didn't want to be judged by some people on certain issues. Then I started to do it on everything, so I wouldn't get friend requests or anything like that. I stay anonymous so I don't have to turn people down and feel like a d*** for doing so. I hate meebo. lol
Because 1) A lot of users will hold grudges, more specifically when it comes to religious and political views. I don't mean questioning people on their mixed views, I mean they hold grudges simply because you believe in "XYZ" & 2) Some people don't want friend requests or messages. They use the site as a Q/A site, not for socializing
Also, I think there's one girl who often asks Qs in the health section and I think she has a dummy account and always awards her main account BA. Both accounts are always anonymous. I never realized it until a few other members told her to stop doing it, because it's becoming more obvious
so guys don't know I exist on this site.
I don't even have pictures up and I still get creepy messages from guys.
It could be recurring users with new troll accounts trying to gain exp points.
