Being pretty new to all this, I can see and agree with both prevailing points of view, it is unacceptable and very dangerous, but also, it happens and it's not worth crucifixion or castration! Perhaps, in an ideal world, all this would take would be the swift intervention of a marshal to "kill" the offender, ideally, immediately and send him back to re-spawn? From what I've seen so far at sites, in my limited experience, if Marshals stepped in quickly, with a consistent line on the rules and variances, it would stamp out this quicker and get us all back to doing what we all enjoy doing quicker?
To be fair to the Marshals, it is a difficult job, a bit like reffing a football match,,,,where the players all have guns!
