That would certainly be consistent with the goals of advogato, but I'm not sure it's practical :)
I didn't say the system was ideal, only that it worked. I consider it unfortunate that hjclub's account was deleted. I did try to convince hjclub that certifying the spammer was a bad idea. I don't know if hjclub read that and I don't know whether the spammer's cert was dropped by hjclub, or as a result of hjclub's cert being dropped.
