So, I pulled the admin who'd originally invited me aside, and expressed that I didn't know these people, and I have SOME concerns. These were not serious, but it looks a bit much to me, and I expect to be hassled more that I had been, by folks I don't really know. I was assure that it wouldn't be a problem, many of the mods were fans of my work, they were here specifically to help protect me and a few others, and ease the work load on again, my swamped admin, now friend. I said "okay."
