I gave them a fake (burner) number in 2016 or so and it worked. I've heard it's harder now but who cares? If I ever want to go on a real shitposting rampage you can buy packs of old accounts for near nothing with crypto if you aren't too particular about the quality of them. I never really used the account and when I did once when the Farms were down in one of Null's threads, I called some faggot a "foghat" and got banned. They gave me that gay screen where you have to delete the post to atone for your sins. As if.
That kind of gay little groveling ritual? What the fuck kind of loser would submit to that voluntarily?
