1. https://chatboxai.app/sponsor_ad and https://api.chatboxai.app/sponsor_ad and why app often get this (reproduce on free and CE version)

2. https://pub-45c0b529c25a4d388dfa7cf57f35f8f0.r2.dev

Thanks for bringing this to my attention! Let me explain:

The /sponsor_ad endpoints were from a very early version where I considered showing sponsor ads in the chat title bar. I later decided not to add any ads since they might be distracting for users.

As for the r2.dev domain - it's just hosting the default chat avatar images you see in the app.

I'll clean this up by removing these unused endpoints and switching to a more user-friendly CDN for the images.
