I want to believe that it's people keeping mum until it's fixed so that the leaked PII isn't spread more widely, minimize the risk of bad actors scraping it all.
Once the leak is plugged, I would hope that Fiverr gets absolutely raked over the coals, this is egregious.
I wouldn’t be surprised if someone wrote a script to pull all the sensitive PII and it’s already on the dark net hacking forums for identity thieves. Freeze your credit at all bureaus if you ever used this site.
