Thanks for clarifying Bison! I understand default behavior of CS:S and the legitimate purposes for block.
I understand server rules and will always follow them, but communities will always suffer from people lacking of common sense. I don't mind with people using block in valid way, but from my experience as a regular MG player it is mostly invalid use. I have several admins in my friends list and I will always clarify certain situations with admins as you desire ! Like everybody I'm trying to reason and help out this community to keep it fun for everybody.
