Github dislikes email “aliases” so much that they will shadow ban your otherwise normal activities for months, and once flagged, support will request not only a “valid” email domain but also that you remove the “alias” email from the account completely.

Likely that they don’t “trust” your email provider, but there’s a lot of strange A/B testing going on behind the scenes of that data harvester.
Setting up a dedicated spare gmail or outlook account solves that issue.
Registering a “cell number” helps too, but it’s hard finding a service that offers “free texting numbers” that isn’t set up in a way that they can see that it’s just one of those services. Wish I remembered what finally worked for me.
Lastly, if you’re using a modified Discord app or desktop install, be sparing with the non-standard features. That can flag you sometimes too.
For most servers though, I find it easiest to just access them in browser as a not signed in guest.
I think Google Voice still gives out a free phone number as long as you tie it to your actual phone number. I used it for Craigslist all the time years ago to avoid giving out my actual number
A lot of services like PayPal will block known Google Voice numbers. Screw all these service for even asking. I can do 2FA without a phone so you must be trying to collect more data than you should.
Are you using 2FA ? With some services (Not Discord but others) I found out that when 2FA is enabled I will not have to suffer endless amount of CAPTCHAs and what not.
