Karma for this post, couldn't agree more with the people getting away with doing certain things, not just once but repetitively.
Throughout my time on LC in the last year I've seen more people get banned for reasons they are unsure of or literally have no idea why, then people who had proof against a person, RTd it and nothing happens.
On another note, Generally when someone hacks they either accept or are worried they will be banned one day, apparently that's not the mind state in this game.
For a reason I won't say in forums for all to see... But some of you know why.
Step your game up GMs.
