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.
It's the closest thing that actually exists compared to what OP has asked for, though. If OP is looking for a list of every single user on here with a negative trust, you would need a compressed text document stored elsewhere (I'd expect to be a couple hundred megabytes at least)
