How to create an account across multiple social media platforms at the same time/automatically?

I'm looking to speed up my client onboarding process, I run an onlyfans agency and instead of taking time to individually create - gmail, instagram, twitter, reddit accounts, I'd love to know if there's a tool or a service that automatically will create these accounts after I've inputted the desired info into a form or spreadsheet.

Ex. I input the desired email, username, password into a spreadsheet, and then accounts on instragram, twitter, reddit are created. Does anyone know of any methods or tools to do so?

making all the accs say on 1 tool / browser, i cant see them lasting long
most decent accounts req the use of multiple browsers to spread
making them on . + lots 4g proxies.
