Some advice I've picked up over the years

A lot of magazine companies (and many other companies that you give your name to) sell your name and address to other companies. Those companies can then send you junk mail.
If your name was john smith and you got a magazine subscription and listed your name as Joe Shmoe. If you ever get mail for Joe Shmoe (other than the magazine of course) you now know that magazine company sold your info.
Using a different name for every magazine would allow you to tell which magazine sold your info

You need to have an IQ above an average brick to understand this.

You start burning every magazine you see of theirs to send a message.
