The Bulk Trusted List Changes tool is new and improved.
This will be a familiar problem to experienced members, especially Mentors and others who help less-experienced members: You help a stranger or a distant cousin with something, and without knowing why not to, they bulk-add you to lots and lots of Trusted Lists for people you're not interested in. This bloats your Watchlist and makes your Activity Feeds less useful.
Many members have asked for a solution to this problem. Some have suggested requiring prior permission before adding someone to a Trusted List, but that's not practical.
What we have done is make it easier to identify the new additions and remove yourself.
There is now a feature on Special:TrustedListChanges that enables you to see just the additions to your Watchlist from the past three months (starting mid-October). This way you can more easily use the "select all ancestors/descendants" links to prune the unwanted ones.
It's also easier to get straight to this, with fewer clicks. See
https://www.wikitree.com/wiki/Special:TrustedListChanges for the differences.
Admittedly, this doesn't solve the entire problem. The new tool will probably work best for those who want to proactively monitor their Watchlists, unless we also add other tools or notification systems. But I think it's a step in the right direction on an annoying little problem that we've neglected for a long time.
