I've just taken a look at the demo and to be honest I don't see it as 'griefing'. I do that alot on that map by which I mean use the chimney as cover and run around it alot. The difference in the video is that there was a prop there.
I don't think it is griefing as such but it does look dubious because it appears as though joshy is about to jump onto the other building using the right side, but sloth is there blocking his path so naturally he has to go back around. I think that if a prop is using that as cover in that situation regardless as to who is around, they need to keep their eyes open - You see a raining Pirate Demo man coming your way you get the hell outta there.
This is my take on the vid (not disuputing it's dubious qualities though)
However I still agree with the other reasons for Joshy's ban i.e. arguing on the server etc although this is also the fault of Eski as Joshy and Eski frequently get into arguments which spam up the chat with capslock. Good thing neither have mics eh?
(touch wood)
Also, I do not think this is about the admins, they are doing their job, regardless of how zealously and conscientiously they go about it. Furthermore, the whole point of a ban is because someone has done something wrong/against the rules therefore might I suggest learning from these mistakes and moving on rather than venting your frustration on everyone else, creating a scape-goat in the form of an admin and not keeping this thread open any longer.
-Is it not clear that it is highly; highly unlikely the ban will be lifted? (especially considering it is just 1 week? --- or do ranks mean that much?)
Good Day Sir.
