it is the under attack mode from cloudflare they give delay of 5 seconds then redirect to site this is an example https://www.anime-planet.com/anime/watch-online/dubbed/
there are some script on github that help with this like when using curl
maybe you can implement it ?
ok just keep in mind cloudflare always implements changes to bypass so better implement a library that is periodically updated also features to be considered
simulate button click : sometimes content is locked behind a submit button to show content
make multilevel scraping for example serial scraping is you load a page with post you click and element then save content sometimes that is not the case sometimes it requires 2 clicks
if these were implemented maan that would be sooooo goood
