I was pissed off lately, when someone shared a link to a #Substack, and the site was using a custom domain, so it bypassed my blocking rules.

So I wrote this little browser extension (for #Firefox), that blocks substack sites more thoroughly, even if they use a custom domain name. Don't drink at the #NaziBar.
