@troyhunt This potentially lowers the barrier to entry for, say, a person looking to harass a former partner. I suspect your feed would be used to track down and aggregate recent breaches by some unscrupulous party. Then again, I'm kind of surprised this isn't all happening already.
@troyhunt If I were trying to compromise someone, and was able to know something about their online habits, your list would make it easier to keep up with finding out what undisclosed recent breaches they may have been included in. It's really just a shortcut, but maybe worth avoiding.
