Affiliate links often inject cookies so if an end-user clicks a marketer's link and does not sign up until a later date, the marketer still receives credit for the sign-up. Did you click on a Chaturbate affiliate link recently? Try clearing your browser's cookies and cache. If this still persists, it can be indicative of a rogue extension, browser hijacking, or general malware.
The mobile redirect would be caused by Chaturbate thinking you're using a mobile device--it might just be your browser falsely reporting your usage of a mobile browser, or Chaturbate misinterpreting your user agent. I wouldn't be too worried about it unless you're getting redirected to an affiliate link, which shows a profit motive. It seems like it could just be a bug.
