Hi, for some reason I can join on servers which are on the blockedservers list: 

https://sessionserver.mojang.com/blockedservers

I tested it with: a8f4b635c3a5ed567c50e427a81d7c2df2f9d7eb and c22efe4cf7fb319ca2387bbc930c1fdf77ab72fc which are the hashes of: *.mineverse.net and *.itsjerryandharry.com

I tried to join on mineverse.net and play.itsjerryandharry.com but both worked without problem.

My goal at this point was to find atleast one blocked server that's actually blocked. I wasn't able to find one. Just "Unresolved hostname" or joinable.
