It's a good idea to have a secondary phone and email for exactly this kind of stuff.
Use ProtonMail for secondary email.
Use Google Voice or a similar service for a secondary phone number.
I don't usually recommend Google services but Google Voice numbers are a bit "cleaner" than BurnerPhone type numbers in terms of blacklisting. That is, Twitter will usually accept Google Voice numbers but may decline a BurnerPhone number, esp. if someone before you has been issued that number and used it to, e.g., spam people.
So you can set up a sockpuppet Google account, then go to Google Voice and sign up for a phone number. They'll ask you for a physical phone number (smart phone, landline, whatever) to verify with. You can then start using the secondary number for social signups without giving away your personal #.
For added security beyond that, invest in a $20 flip phone from Walmart that can make calls and receive texts. Use a nickname when activating. You'll literally only use it for site verification, so buy a $10 pay-as-you go card and stick it in a drawer. No need for a monthly plan. Then use THAT as the verification phone for Google Voice.
All of the above intended to shield you from casual harassment by moderators and employees who may have access to your account info. Obviously if someone with power or authority wants to find out who you are, they can talk to the phone # provider and get that information. The point here is to discourage casual doxxing vectors as well as prevent your personal email and phone number from being banned/blacklisted. Only expose throwaway emails and phone numbers to Big Tech, except for your primary personal account, if any, which should be kept clean.
