Craigslist "send to state for investigation"

[Brian L.]

Hello everyone. I placed an ad on craigslist yesterday in Real Estate Services; its a simple add that states that I buy houses. There are no false claims, not asking for money or anything like that, just a simple statement, a link to my website, and a phone number. Well I just got an email from craigslist and it just has my ad heading and then the body of the email says "send to state for investigation, cc". What does this mean? I did a quick Google search and didn't find anything info about this email. Did I do something wrong?

Here is the ad, seems okay to me but this email has me a little worried. I have never had a problem with craigslist ads before.
