Don't use tor browser. Make a tutanota or protonmail account and wait for 2 days. This will make sure that your account doesn't get locked when you receive the Twitter OTP like 5 minutes after account creation.
Use Windows or Ubuntu with VPN. Passing the captcha for creating an X account is a lengthy process (10-15 minutes) but it's faster on ubuntu. Then keep liking, retweeting, commenting and eventually your reach wlll increase and more people will see your activity.
Don't forget your email password, and try to keep logging in from the same VPN country. If the location changes they might ask you to enter the OTP sent to your email, so it should not be a disposable email.
What VPN are you using? Mine didn't work.
Have been using Proton VPN (paid version) and Twitter regularly on several accounts since 2023. The accounts I created and used in 2024 are mostly on Ubuntu. Still no problem with the ones created on Windows in 2023, can login fine. Sometimes it's a bit slow, but it works.
One time this year I tried to use ceate an X account on Windows but it took too fucking long, so I gave up and booted up my Ubuntu laptop. Was able to create it in like 5-10 minutes.
Both using paid version of Proton VPN.
I'm not signing up to Proton VPN without actual confirmation that this will work in 2024 december. ;)
