I don't know what you're referring to, but I think unethical may be overstating the case. Unwise, maybe?
Mostly, though, I think: why do you care? I don't know if it's my age, but I can't get emotionally connected with the MN community like some posters seem to. I love this site, it's such a useful resource and I've got loads from it. I've also connected with some individual MNetters and moved that into RL friendships that mean a lot to me. I've been here for donkey's years. But it honestly has never bothered me that, under any of the names I've had, I've never been part of any in group, been a 'popular' MNetter etc. Because MN is, after all, just a kind of interactive magazine, isn't it? I enjoy it, but I don't need it to enjoy me.
