I used to do that, for similar reasons, but stopped and stuck with the random account I happened to be using at the time. The reason? Nothing more than HN has the least solvable captchas going and I was tired of a dozen attempts every time I create a new one. I still think of it as a throwaway though, so don't care about the karma or pay heed to it. Ironically the comments I expect to go heavily negative often attract the highest positive response.
