Unannounced blockings, in my opinion, are quite rude.

This has happened to me more than once already that I receive a notification blocking me from further favoriting any more artwork by a certain user, yet they do not leave a private message (note) explaining why. Today, such was the case with Goof_Sosiska324.

From now on, to any user who wishes to block me, just because I favorite their artwork: PLEASE NOTIFY ME FIRST!
