Im so lost whats happening and whats with all the codes

The code is for getting free ink when signing up on the tap@s app. I explained it in more detail here: https://www.mangago.zone/home/mangatopic/13911604/

This is happening because the author messaged the uploader to delete the chapters, so people are moving to the legal app to be able to keep reading, since it’s pretty easy to get free chapters there.
