For threatening legal action, squish7 has been banned.
As a reminder to everyone, threats of legal action, either against the SDMB or against another user, are an insta-ban offense. Whenever someone threatens legal action, we moderators have no discretion in the matter. We are required to ban the user and forward everything to our admin so that the legal folks can be notified. There are no exceptions in this rule.
