So, since posting the warning about the site Prabook, my blog has been getting regularly hit by bots from Russia, China, and other countries hot for identity theft. Coincidence? I don't think there's anything they can really steal or do, and we're pretty careful about identity theft and that sort of thing, but if there was ANY doubt that Prabook wasn't a totally malicious site, I certainly don't have any now.
So, if you find yourself being given an unauthorized profile, the email to contact them is firstname.lastname@example.org. Because they won't let you block your profile even if you request it be taken down, I would also report them to your state's consumer protection division in the Attorney General's office, and keep a copy of your request to have your profile taken down.
