I don’t see anything there about querying license plate databases. There is a spreadsheet of donors to some kind of organization.

I don't know what they think they're doing there. If the most interesting thing they found was the public website leading to a fundraising platform for mutual aid a) there is literally nothing illegal there, and b) you can find that website linked to publicly by conservatively 25% of the twin cities population. It's literally the most prominent fundraising website anyone has been posting.
