She's either outing herself as a liar or illegally hacking into data. It's almost certainly the former and that's why sites like this exist. They hate people outing their lies, dishonesty and having accountability. It's all #girlboss #buisnesswomen until someone politely asks about an undeclared free holiday or AD then they cry they're a victim of a hate crime.
Nothing illegal happens on tattle - this isn't North Korea and you're allowed to comment on public figures especially as these people put themselves forward for it. We have strict rules so no hateful, abusive, threatening content is allowed here.
People can only be outed by the information they choose to post here, not even admin could identify users -
IP address (this lie that influencers spread explained here) are pretty meaningless and all they really give is the ISP then a court order would be needed to trace a user. But unless anything illegal happened it would never get that far. Tattle admin would be the first to call the police and report a user if they felt they were a danger to someone, and I'm sure all users would support that.
One common trick people trolling on the instagram forum here use is "check out bla blas story" then the troll can find out your IG name from viewing a story. But many here would'nt even mind being outed as there's nothing wrong with gossip on a public figure.
However if she has hacked into data here that is a very serious crime.
