When I first joined Toribash, I joined social groups as an alternative way of contacting some of my early clan-mates & people I met in-game. Now, it has simply become a joke and something I do when I have time to kill; hell, I'm in over 250 of them.

My question to you is: Do you use social groups? If so, why and how?

I only use and keep on checking my fanclub which is a social group.
If you asked why, because it's fun is the most suited answer for this question. Most of people like to make their own fanclub, and do a wibbly chit chat and stuff.
And if you asked how, it's easy. Since I made my own fanclub group, I can easily open it with the url on my signature, or I just can easily open it in User cp->networking->social group and my fanclub is right on the "Groups You Created" menu. So, It'll be easier to open it even if I'm being a member of 200 social groups or more.

Yep, especially we could spamspamspam
I use it for a wibblish chat as Raiken did, or I could discuss a candidate of my clan, secretly

I don't see groups, maybe the MAU group because it's the official group of the clan I'm in.
but seems interesting to see how much members are in one group, like a fanclub.

i like to talk with others ad have activity in the group
sadly most people dont use them...i created a taekkyon group but not much people uses it
