Actually, the most common thing now isn’t plagiarism, because the traffic gained from plagiarism is limited. Instead, reposting high-traffic content from other platforms is the easiest, especially short videos, which are also pretty hard to 'plagiarize.' I’ve heard there’s already an industry chain for exploiting X. Crazy acquisitions or collaborations with high-followers X accounts, then constantly reposting short videos from other platforms. You can even automate it—just come up with an eye-catching name and you’re good to go.
