Who knows what they intended? It's probably not very nice to load them up with extra spam just because you're lazy (? I mean really, what are you gaining here?)

Who knows what they intended? It's probably not very nice to load them up with extra spam just because you're lazy (? I mean really, what are you gaining here?) I own a domain that is similar (in a "1337" way) to the domain of a CRM SaaS operation. At least once a week one of their customers signs up using my domain in a throwaway fake email address. I find it extremely frustrating. Because of their architecture and mine there is no easy way for me to filter these messages so I am often stuck with the spam in my inbox. I don't hold a grudge or anything, but I wish people would think before they fill in someone else's perfectly valid info into a form they don't want to give their own info to.
