This is completely not related to the thing what OP is asking for.
Bpip.org can give us some reports but not the complete list of negative trusted members.
You could use the list of all DT-members to scrape all ratings they've left. That would "only" require scraping (give or take) a thousand pages, and gets you a list of all users with negative trust.
That approach is much faster than scraping 2.65 million individual profiles (but a bit more work to set up).
However, since OP doesn't explain why he wants this list, I'm not going to create it.
