I understand your point of view Anthony, and I am not trying to say that this is in any way a forum for children...
I think it would be a good idea if there was a period in time given to a banned user to contact an admin and try to explain if there was a mistake made, mistakes can always be made e.g. someone posing as someone else or w/e.
I think 3 chances would be better? depends on why they have been warned, little problem or big problem?
Glad to see this system though
No I think 2 is good maybe to good! Why should people even get a chance it give's them a chance to do one thing bad would you wan't scammers on this website I think not. So good idea robonson
