Yeah, I've experienced the same and it's really a pain in the ass. Apparently there's tons of orgs that can automatically add sites to that blacklist, I got abuse from some company saying there was a phishing page on my IP because it featured a login page and the text "Amazon" and suddenly chrome started showing alerts when I visited the IP.

As with most of similar systems (spamhaus etc) the people running them are just as bad as the people they're trying to stop.
