~10 years ago I made about 10k Twitter accounts just for fun. I never used them. They still exist, no one deleted them. A while ago I lost the script and password for them.

Back then you could bypass captchas and other checks by changing Tor endpoint (some endpoints required captchas, some didn’t). Made a script that did just that.

It also worked for Facebook and I still receive facebook spam for those accounts daily.

I have no problem with asking for a phone number during registration, it complicates automated account registration and makes it quite expensive. But I dislike the idea of hiding content behind login page, internet should not be a walled garden.
