I accidentally clicked block user when I was supposed to send a message. Will the person know that I blocked him?-I immediately removed him after I blocked the person, then sent the message. Will he know?
no. I have done this several times including alliance members/leaders with whom I chatted a lot. I would have heard something if they saw something.
I am not sure if (s)he sees something when (s)he tries to send a message. I'm also not sure what happens to a blocked message.
