Disposable email addresses are rejected
Sign-up, the email step after X or Instagram sign-in, and checkout all refuse temporary-mailbox domains. Use an address you keep.

What is refused
Addresses at known disposable or temporary-mailbox domains. The sign-up form and the email step after an X or Instagram sign-in answer "Disposable email addresses cannot be used. Use an address you keep." Checkout runs the same screen before it starts.
Why
Receipts, refunds, password resets, creator decisions and payout notices all go to the address on the account. A mailbox that vanishes in an hour leaves you unable to prove you own the account, and it is the usual signature of self-referral and payment abuse, which the terms prohibit.
If your real address was refused
Some privacy-forwarding domains are on the same lists as throwaway services. Try another address you control, or email support@slopsquash.com with the domain and we will look at it.
