There were 3 who tipped over $500: Temp, Goksha, and the new "Whale".
My guess is that they simply filled their Fansly wallet and can therefore tip more. In this way, Fansly has already "processed" the money, and the payment processor may no longer have access to the money, which makes a chargeback more difficult.
Or maybe they just increased the limit for everyone and didn't update their TOS.
