Read the whole discussion. All you have to do is upgrade your account to a business account (it's free), and add your business name. This works for twitch or any other online payments. Just make sure to walk through all of the settings, invoice settings, privacy settings, etc. to make sure there is no "business contact person" (which would be your real identity) and your address and phone, etc. are disabled from invoices.

Use a third party designed for twitch streamers and enable Paypal as a payment method there.
