What, like customers not wanting pics of their property used on your site? Never been an issue, but I have a photo release as one part of my contract, stating that I retain the right to use all drawings and photos in my portfolio and other marketing efforts but will not disclose address or other personal info without written permission.
Spam has been minimal, not sure why. My biggest problem is older folks who don't get how Google works. At least 2-3x a spring I get a call from someone who typed something like "cheap vinyl fencing" and because I must have mentioned that phrase in a blog post, I'm on page one. When I tell them I don't do that they start screaming at me for false advertising on the Google and I better sell them a g-d fence panel if I know what's good for me. Seriously. People are weird.
