Why was that information available on the internet?
That's the kind of risk you take if you make that kind of information available on the internet. Think of all the possible things someone could do with your address and assume those will be done. That's the type of precaution you should be taking.
Why were you selected over any other business owner? Just seems odd you would be selected at random and then two different people would make an effort to drive out to your house "for the lols".
Sorry, if I go into details it'll be pretty obvious who I am. My entire point is that internet trolls aren't just some sort of harmless fun for a lot of people.
Doxxing a business owner is generally very straightforward even if they take careful steps to hide their identity - there's a huge paper trail behind any real business.
If you think you can't be doxxed, you're probably just lucky.
