To get rid of the annoying YouTube message (ad blocker are not allowed on Youtube) use this custom filter in uBlock extension
- Open uBlock extension dashboard
- Open my filters tab
- Copy & Paste this code into my filter
- Apply changes and close all tabs

Some of the sports streaming sites have done this too. Any ideas if this will work there ?
YouTube filtering is fairly unique to YouTube since they serve ads so aggressively so it's unlikely to help on other sites.
J guess you need to adapt the code fot the page in question. If you read the code, it is setting some values to variables youtube checks for.
