Banned people could be posting if they have found a hole in the forum security or hack and taken control of the forums.
There was a case in Australia where a hacker took over the NBN Nantional Broadband Network posing as an administration for almost a week until someone twiged to it
I do not know what all the hullabaloo about banned people is about. So what? Theoretically one who is banned can still post here, all one needs is to have/buy 2 copies of Trainz and register each under a different user name. No need to hack (or slash) anything, just use one until banned and carry on posting with the other (theoretically speaking of course!).
To be banned can happen to the best of anyone in any of the different Trainz forums here, this does not necessarily mean a poster getting banned here has to be nasty or obnoxious. I can speak with experience about this but this again is a different subject.
So everyone has had their say it appears, so I'm closing my own thread. I was just trying to be helpful here. Learned my lesson all, won't happen again.
