If you're running server-side GTM behind a custom domain (Stape, Taggrs, GCP etc.) with some additional anti-adblocker features, it's worth knowing this isn't bulletproof.

The filterlists are not only pattern-based (/g/collect and /gtag/js , sgtm etc). The whole subdomain can land there... And actually, there are around 50k custom sgtm subdomains blocked around the web.

I built isblocked.fyi to check this. You can type a domain and see every major filter list it's currently on (EasyList, EasyPrivacy, AdGuard, etc.), when it was added, whether the block is full or third-party-only, and which blockers ship that list by default (uBO, Brave, AdGuard, Firefox, Edge, Safari, DDG).

It's free, no account needed to search. You can set up monitoring after signing in. But no paywall anywhere.

If a result looks wrong, happy to fix it! Hope, you'll find it useful :)

Here's the replay of the piece being "mined" in 5 days and 10 hours using a pixel-by-pixel "mining" technique (2000x speed). I call it mining because the algorithm translates a SHA-256 hash into an RGB colour, then checks whether that colour satisfies strict visual constraints before the pixel is accepted. That check creates natural difficulty for proof-of-work driven by visual rules rather than by counting leading zeros, as in Bitcoin mining. The piece is not rendered in advance, nor gradually revealed from a predetermined structure. After each pixel is mined, the system does not know what the next pixel will be.

The full journey since April 2024, and a live piece currently mining: determined.ink

Really curious about your thoughts! That's my first public exposure of the project.
