If you monitor the public for rent posts you could mine that data over time. Most units turn over every couple years it wouldn’t take long to get a complete picture. You just wouldn’t know the incremental adjustment though you might be able to buy that from a broker

I'm asking because it might be evidence of pricing collusion.

Depends on the market. For instance in my country, all rentals need to be register and the cost is public.

Which is why I want to know how they got that list.

I don’t think there is significant desire to prosecute so non issue
