What do you want to know TerfAndSerf? Stephanie uses multiple names to incorporate companies, which are compulsorily wound up with out paying taxes. Stephanie also has various Twitter aliases. Stephanie has a (cousin?) Jamie, who is even bigger on the company formation side. Stephanie harasses women on Twitter. Till recently there were some Youtube videos of Stephanie, as a man several years ago, including one where Stephanie harasses a couple at their home. Stephanie also created some stalker Twitter accounts which call the wife of that couple misogynistic slurs, accuse her of 'drinking her husband's wages', being a 'bitch', and so on. These are mostly still up on Twitter.

You can find Stephanie & Jamie's companies quite easily on Companies House. But there are some which are too old to appear, so I'm not sure what happened with those.
Stephanie uses the initials SRH, and previously used the initials TGSH. They have weird usernames like TGSH2009, and SRH2018 with a year after the date the username was created.
