Charles, compliments will get yiou everywhere
I am only sharing what I have heard and read-It seems that alot of spam is an information grab of anykind. I always had the same inclination as Ron19, to mess with the spammers and scammers.
The problem is that alot of this stuff is generated by "bots" also called autobots or auto-responders, so sometimes this stuff never is seen by a real body its just cycled by a computer program.
I am not an expert; it just seems that being smart, coding them as spam and hitting the delete button is as much a body blow as sending them an email.
Just a few things to think about,
later.
