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.
Some crazy lawyer included my parents in a traffic death suit’s defendants while they were victims who had their car badly damaged when the reckless driver rammed into two cars (including my parents’) and two pedestrians. The question isn’t whether you’re at fault, it’s whether you want to risk getting a court summons.
Admit no fault, ignore the criticism, keep doing the same thing, receive no consequences. I wonder how the folks at Fiverr's Tel Aviv HQ learned this strategy.
I've never been in the position that I've had to deal with this. Is the best you can do in this situation to pull the files and optionally republish them to a robots.txt'd path (with authn/z, too)? I can't imagine you can get it pulled from search engines very quickly...
There's a way to submit a request with Google ticket content taken down and then the easiest way would be probably to do a no index in the header response for future content
My guess is that if they take down the public hosting, most clients would lose access to work they paid for and fiverr has no way to put these back behind an authorisation. It is just a public list of files, either everyone has access to your file, or do not, including you.
My guess is that there is literally no one there who knows how to fix this. Seriously, look through the proposed solutions here, plenty of devs wouldn't know how to do any of them. It might not even be possible, with their architecture, to fix it quickly and retain functionality. I have worked in a place full of noobs where I'm certain none of the devs including me would have the first idea how to fix something like this.
