I've experienced similar issues with the unofficial X post API, and I've found that rotating auth tokens and ct0 values can help mitigate the 403 error. However, I'm curious to know if anyone has tried implementing a delay between API requests to avoid triggering the logout mechanism. Has anyone else noticed a correlation between the frequency of requests and the likelihood of accounts being logged out? Additionally, clearing cache and checking connected apps is a good troubleshooting step, but I'm wondering if there are any other factors that could be contributing to this issue.
