You can actually contact discord support if you don't want to provide your phone number to them. The reason it's required that you provide it is for security of the server, so bots can't join en masse and things like that.I’m beyond pissed that I had to give my personal cell number fthat only my lawyer has for verification to be on discord. Now that I have everything is ready only. If I get anything from the server other than that code, it won’t be pretty. My family has been harassed, threatened due to my lawsuit on our old cell numbers yo the point I had the company put them on hold and got another me number for emergencies.
