According to the new information I have gotten it seems that Art's exploit were not as serious as we feared it once was, he was only able to extract the login information of a few accounts that were not connected to any crew's private section.
However I still recommend that you change your password so it's not the same as it is at the PKS forums if you have an account there.
Art is banned for 2-3 more weeks, not for the severity of his crimes which were basically being told/sent things but for what he was trying to do, that said he did not leak anyone spots/stunts nor any inside information from any networked crew through exploits.
Let's all use this as a reminder to make sure we don't toss around sensitive information and access about ourselves and our business to other people who don't know if we can trust or not, as will I.
