Leaving a paper trail of you having accessed unauthorized private info is a bad idea, some crazy lawyer could decide to include you in a suit. Just not worth the hassle. Email a tip line about the general situation.
Not to forget some eager prosecutors. They can still try to prosecute for accessing material even if they end up losing. Lot of hassle there.
Good call!
How is it unauthorised if it's freely available via a search without having to bypass any login?
It'd be like putting up an advert and then trying to sue anyone who sees it.
