The code is supposedly locked except for business purposes. It's absolutely trivial to buy followers on Twitter, and there are huge rings of "follow for follow", etc. It's painfully cheap to buy followers, $3/100 followers is the high end. For $300 you end up with 10,000 followers. So for a few hundred dollars and some sucking up you can get a ton of followers and a blue check mark. Twitter influence is completely fake and it's no issue for the rich, famous, and powerful to spend thousands of dollars on followers to have additional influence. Stopping that would be one of the highest priorities for making twitter less of a liberal shithole.
