Can someone explain the legal action?

Ok so I follow a few women on social media who are MLM Huns and one in particular made a long post a little bit ago saying she just finished a 3 year long battle with it works (didn’t name names but I knew where she used to be). She said she decided to leave the company and then they tried to sue her for 7 figures in damages. What would they possibly have to sue her for for simply leaving the company? She said she had to sell her house and move to a different state to pay for legal fees. That’s insane and really sad that this massive business is going after families like that.
