That being the case, go to the google groups to request a account. Please change password. Given our recent rash of vandalism the last thing we need is an open account laying around.
But I'll post the question on the groups as well if you don't have an account there. Or wait here to see if one of the people that grabs images posts. Usually, they check here at least once a day, so there should be a reply.
Links in my previous comment for the page of links.
Also, feel free to join. Sounds like you've never been. If you like yukkuri fiction, there's a ton there. But as a fair warning, most of it is going to contain unfamily friendly situations, if that kind of thing isn't to your taste. Lots of creative, and diverse work though. Also try the site to help read summaries and see if any sound to your liking (site is incomplete)
From here, you go into the Yukkuri Bullying threads; they're the ones that have "ゆっくりいじめ" in the picture. They're also usually the largest thread, by far, on that board. The current one is http://jun.2chan.net/51/res/255739.htm. Threads tend to last 2-4 days. This board also has other threads, generally involving Jissousekis, as well as "classic" yukkuri pictures and general yukkuri discussion.
I have absolutely no idea where to go to actually make these images.
