Comments could be seen from their account only, same with submissions. Voting/modding would appear to affect the total, though the number being tracking is the pair (total real, total real + total fake), with display based on banned status.

The idea is that there is little to stop someone from making a new account account if they note they are banned.

A similar scheme could be used on an individual basis for trolls. If you mark a troll, you can't see their comments, and they can't see yours. It would fork the audience, but the hope it would eventually be bipartite: trolls on one side, people that matter on the other.

Sorry if the article I wrote seemed like common sense. I was trying to point out why the home button has become web convention. And point out placement of content in relation to that.

FishTrain is my site. Why should I be banned for submitting articles from my site? Are there rules against this on YCombinator?

I was under the impression that it is in bad taste to submit your own articles to social sites like news.yc, reddit, and Digg. It appears that you submit every single article you write. (And some, honestly, are good-- far better than this one.)

If you took the time to write it, and are willing to share it, why not submit it? That's always seemed silly to me.
