Phone number can be problematic to share in some areas of the world, so it does depend on where you are, but email shouldn’t be an issue in general. So easy to get an additional, private email address and use both at the same time.

I also don’t have most mainstream social media anymore but have noticed a significant drop in people asking for it these days. Might just be my location in a city with a lot of progressive, tech savvy people, though.

I mostly use phone number and/or Signal these days.
