People can make poor judgement decisions sometimes and second chances are most assuredly a good thing to have; not only in a community of at times immature, hotheaded, and juvenile participants (myself included) but also in all facets of life and social interaction. How would you like to have made a joke in bad taste and forever have a group of people look at you as a "shitlord"?
Downloading, installing, then using a hack with the specific intent of disrupting 12 other people's game is a on a whole different level than telling a bad joke.
I don't understand how you could possibly even think that hacking is a good idea, ever.
It doesn't really matter that you admit you're hotheaded and juvenile; from my understanding what you did goes far beyond a reasonable level of "dumb" and into "you probably shouldn't ever play pug.na ever again."
