Yes, it is. The link that you've provided I guess is already useless as this doesn't accept anyone anymore. There are a lot of ICO that offers twitter bounty campaign in which you could earn Bitcoin and Ethereum (Tokens). Though, Today CM's do have minimum requirements before you could get accepted.
Ok, now I am curious. Besides all the posts here about Twitter bounty campaigns on bitcointalk for crypto, is there any OTHER way to make Bitcoin with Twitter? I must have created more than five accounts on either Twitter or Facebook every time I need one of those accounts to join a site (I really hate that actually). But then I never remember to save the emails or passwords.
But if people really are making a lot of Bitcoins, I would like to know. I see payments here not really worthwhile for the effort of having 100s of followers.
As far as I've noticed, The only way of earning coins via Twitter is by joining those campaigns and nothing more. Also, since twitter audit is part of twitter requirements. If you are a pro member on twitter audit then you could offer that service to earn extra Bitcoins. Since you have the privilege to have unlimited counts of audits.
