A play store advocate can not look up why your app got rejected, they can at most ask their play store colleagues to look it up and to contact the app owner.

It is this way to avoid getting in a situation where being friends with a DA is an huge advantage.

Their job is to collect dev feedback, as well as evangelizing good practices.

And granted, both teams could do a better job at pinpointing the issues (and devs might also try harder to follow the rules .. fwiw play store bans threads have just been banned from r/androiddev because devs had a tendency to forget to talk about the legitimate reason why they got kicked out)
