A controversial feature request- when a new account reaches a negative karma level within a certain period, HN will display all other usernames associated with the IP address of the throwaway.
I like the idea of an incubation period, but I've seen valuable comments posted from new accounts- I bet a ton of people lurk for months before seeing a thread they feel they can make a valuable contribution to.
I do have a CS degree, but I must have missed those classes.
It will not be made known to the user that their posts cannot be seen. They will have no reason to use alts, and we will have no reason to IP tracking, which could affect non-troll users.
For example, you can objectively say that Hitler was an influential head of state (e.g. starting WW II) and FDR was an influential head of state. These are both true statements, while at the same time, these were two very different men.
