Scams 7 (video has a typo, but I'm too lazy to redo it)

You don't have to give your real phone number or your real email address to all of these different online platforms.

You can use a service called Firefox Relay.

The free version of it allows you to create pseudo-email addresses that will forward on to your real email address.

The premium version will give you a custom domain and it will also give you a fake phone number that you can use.
