You know, it's amazing what anonymity will do for people on the web.  If someone is interested in contacting you for what ever reason, be it any level of comunication, enough to write a message to another user, wouldn't it be courteous to at the very least reply with a "no thanks", or "not interested"?  Master/Dom/sub/ or whoever you are?  You never know what you might miss in a momentary hasty decision to ignore one who takes the time to say anything to you.  Not being rude, just a little shocked at the blatant disregard for others sometimes.  Hell, I don't know them, they don't know me...they don't interest me...fuck 'em.  That's how it feels.
