I would recommend if you receive a admin message to do the objectives to attempt them and not troll the admin enforcing the rules.  It is one thing if a player complains of you not doing the message, but in this case it was an admin probably using admin chat.  You can camp and still do the objectives.  It just takes a little time management.  Regardless you know ruplayer is an admin.

In the future if type record "name" in console you could show that it was abusive.  The chat logs illustrate that you had it coming to you.  Be advised that since you have a ban, next time it will be longer.  Learn from this, listen to admin and have fun, and if you see green text directed at you...listen.
