The group hasn’t been active for many years now it looks like, but the group page still exists.

Group founded 2004.
There’s not much in the group gallery now, so probably I was looking in the individual galleries of some of the members and I think some of the time some member would make something and post it to Albino Blacksheep and sites like that and maybe post a journal entry about it to their own individual journal on their own profile.
deviantArt also had IRC-like group chats. Flashers had a chat room. There’s a link to it still in the about section of the group, but that link doesn’t work any more. Even if a group didn’t have much posted into its gallery they could have a lot of member activity in those chat rooms. And from what I remember, I think I visited the flashers chat room a few times and that it was pretty active.
I think some chat rooms were private, and some were open even to people who were not in any particular group.
Definitely remember Stick Death in highschool around '99-'01, 2+ years before this flashers group supposedly started.
I did think Stick Death came out before Xiao Xiao?
