`  :But, why does that happen? What’s the point of the whitelist if HG is only going to re-add someone who has been removed from it? On the other hand, I see your other point that by removing someone from the whitelist, even edits to their own talk page will show up on HG screens. Ultimately, the whitelist is meant to include individuals who are not likely to vandalize, which I believe the editor in question is not likely to do. However, WP:Huggle/Whitelist states:This is a list of Huggle users whose contributions may be ignored while searching for vandalism.So, since the editor in question is no longer a Huggle user — he is no longer in the Huggle users list —  the program should not have put him back in. So, it appears to me to be a glitch. But, there is no real harm here since this particular editor is certainly not likely to vandalize. But, it is a conundrum. Thanks for the note! — '''''' `
