A Twitch streamer, TikToker, YouTuber, and OnlyFans model, he[c] began cross-dressing as a campaign in which he would dress as his e-girl persona Rose for a month if he received a certain amount of money in donations.

In March 2024, he came out as genderfluid (preferring he/him) and shared that he had started feminising hormone replacement therapy, saying that through cross-dressing "I'd uncovered a part of myself that I had been purposely shutting down".

[7] Issy van der Velde of TheGamer criticised Twitch for "deciding a streamer's gender for them" and posed the converse question of whether a masculine-presenting woman would be exempt from the policy F1NN5TER was said to violate, also expressing concerns about how the rule would be applied to trans men.

[1] F1NN5TER announced an intention in December 2022 to donate to an organisation, and in May 2023 chose GenderGP, the only private provider of healthcare for transgender youth in the United Kingdom.

[9] The same week as his 2023 Twitch ban, F1NN5TER was quoted in The Mary Sue for his response to PragerU's criticism of men wearing women's clothing: "But what if it’s reeeeaaallly fun".

As a result of his OnlyFans modeling, he has stopped doing Minecraft streams, to avoid attracting a younger audience for whom his adult content would be inappropriate.
