So far, the most credible result I've gathered is that the current wave of account bans is due to the prohibition of crawling data from Twitter's official API.
According to previous official quotes, if a business account wants to retrieve 200 million tweets, it needs to pay over 200,000 USD per month. For companies like gmgn, ai16z, and eliza that do Twitter searches and automated replies, the request volume should be around 1 billion per month.
Some companies, in an effort to save costs, resorted to third-party crawlers and were collectively punished.
At the same time, it has also affected the bloggers who previously mentioned gmgn and ai16z multiple times, as they may be considered related matrix accounts.
This explains why many web3 task platforms have struggled to stay afloat; the API costs have gradually exceeded the platforms' revenues. Every time a user completes a Twitter task and goes to verify it, the platform has to pay to request a batch of data.
