This process gives rights holders a legal mechanism to get infringing content removed, but it also means X's response to copyright complaints is governed by the DMCA safe harbor framework, which limits X's direct liability.
By using X, you grant the platform an extremely broad, royalty-free license to use, modify, and distribute your content worldwide, while X's financial liability to you is capped at just $100. X can suspend or terminate your account not just for rule violations, but also for prolonged inactivity or what it deems 'commercial inviability', with limited recourse available to most users. You can deactivate your account at any time by visiting your account settings to terminate the agreement.
