It's time to end this small talk.
1) You filled out an online survey or form (magazine subscription, etc.) and they sold your information to these guys
2) They have a bot that found your information on the website
3) They manually looked up your business name that the site displayed (if you're registered with the city/county/state to do business)
Okay - it's been fun. The point is that HOSTONY didn't give it away or sell it.
