PSA: I get more of these than I can count and they just go straight to my junk folder. I read the subject, look at the sender, and usually just move it to spam without ever even opening it.

I actually use the affiliates listed I list on NixNet. They didn't contact me to gRoW tHeIr BRanD or anything like that; I used the service for a while, decided others might find it useful, looked for some kind of affiliate program, then signed up for it myself.

I derive genuine value from them, they're not just marketing spam to pump some crappy startup.
