unsubscribe messages

Is anyone else getting message saying that you have asked to unsubscribe from Sailnet and asking for confirmation ? I've gotten three in the past two days. I didn't ask to unsubscribe but it started after I made the comment that I couldn't post from work. It may be a spammer or even someone looking for passwords. Just interested to know if anyone else is getting these. Mike Kennedy Conquest Cal 40 # 96
