Being Ignored Is Worse Than Being Copied
It is better to have your work pirated than to be ignored as an artist.
In the same vein, it is better to have people viewing your website but blocking your ads, than it is to not be viewed at all.
Implementing ad blocking detection, and preventing someone from viewing your content doesn’t make them disable their ad blocking software. It just drives their eyeballs to easier to consume content somewhere else.
P.S. I have statistics and analytics and data to back up my argument on both of your opinionated objections.
P.P.S. Copyright infringement is still copyright infringement and no, you aren’t “doing the artist a favour by getting them more exposure” by distributing their work illegally.
