How frequently is this happening? Maybe you can publish a list of who wiped their list (and who wiped all their inclusions) each week on loyce.club

I have found that it is very difficult to create a good trust list, even if you have only a small number of people on your list. There are a fairly large number of people who I have found that I am willing to trust their ratings, but are very bad at creating a trust list of their own. As you have seen with the very large number of trust exclusions in your trust network, someone with a fairly small list will likely come across a large number of people in their trust network whose ratings they don't trust -- if someone is forced to add enough people to their exclusions, they will eventually give up and go back to using DT.
