I received a private message from a company for something I was absolutely uninterested in. I actually was set to allow communications when I shouldn't have been, so this was partially my fault, but the message was spam. I was given an option to choose if I was interested, and it seemed to indicate that saying I was interested would send a message back to the person.
So I chose that I was not interested, and a comments box appeared. So in the comments box, I typed:
"This looks like it was a spam message sent out to a large number of users in hopes of finding a needle in a haystack. I do not appreciate receiving job offers in San Francisco when I am not located there."
This message was then sent to the employer, who responded today with a nasty message telling me to RTFM:
"Your assumptions of spammy malice are mutually unappreciated. One of the thinks that makes Careers 2.0 so great is that employers cannot send out large volumes of messages mindlessly ... If you want more targeted messages from other employers, go RTFM, set the geographic preferences, and fill out your profile with more detail."
I replied with this:
"That message was not intended for you. I chose NOT to reply, and filled in that text as feedback. I'm sorry that it was sent to you."
I would hope that we could clarify in the interface that even though you are choosing that you are NOT interested, any comments entered will be sent to the employer, and not just used by careers.SO as feedback, which is what I assumed.
