mys don't take @CyberGene's reply wrong. They are free to provide their opinion, but this Proposal isn't much about opinions. You have a valid proposal, which is to create an extension that detects ad blockers and act on them. Once such a proposal gets traction, either by upvotes or comments, we can look at opening up a bounty so that someone can execute on it.
However, considering you already resolved this with your own solution, I feel there's currently no need to prioritize this. Is that correct?
