Is this how it really is? That a person can log in under two or more pseudonyms, build up experience in both, and then use the logins to comment on his/her alter ego's posts, and even vote on such posts?

Maybe I am a little naive, but this suggests to me that the system can be seriously abused. When people use pseudonyms, trust becomes very important. The recent controversy over logging of the chatterbox is a case in point. The use of alternate logins is just as serious, in my opinion.
