It's called #censorship and yes, #transparency does not really fit their bill. They do what they want. #Fedibook
My advice: at least find an #instance that takes its clients seriously and feel free to expose those who don't.
At a bare minimum each "block" must be publicly justified but ideally, there should be fair and honest communication beforehand. Sadly, we don't see that happening much anywhere.
