Re: [PLUG] OT: Spam


I have a stupid question and I would really like to know.
Spammers exist by pissing people off.  Do they really make a
profit from it?
Do the companies that pay them to do their thing really realize a
profit from this operation?
Do they really get that one response for 99 angry deletes that might
make it worth while?
