I know this is a warning we hear often, but we're seeing many Twitter accounts being hacked lately. Please be careful with your passwords and reset them on a regular basis. If your program or station account is compromised, just reset the password and be sure to send a tweet to your followers that acknowledges the spammy DMs they received. These things happen, but it's a courteous and positive thing to let your followers know you feel bad and have remedied the situation.
