If you’re using UBlock Origin do the following:

Go to settings. Go to Filter Lists. Click purge all caches. Click update now.

That’s it, this message should disappear entirely.

I think there is going to be a time when ublock alone cannot simply program their way out of this, they will need help eventually from a completely different approach like anti ablock killers or some other app that hide the blocker itself from detection
