Hi, I'm Christian Calabrò 👋

Performance marketer turned developer, based in Italy. I build products that help small businesses sell more, then sometimes I open-source them when the market gets harder than the code.

Facebook Ads fill up with crypto bait, follower farms and WhatsApp numbers within an hour of a post performing. The tools that fix that are €30–200/month subscriptions that keep your Page token on someone else's server. CommentHide does the same job as a single Cloudflare Worker in your own account, usually for free.

It is a rule engine, not a blunt switch: seven rule kinds, a dry-run mode that records every verdict without touching Facebook, and a stated reason on every decision. Spam gets hidden. An unhappy customer does not.

• Stack: Cloudflare Workers · D1 · TypeScript strict · Hono · Meta Graph API · zero runtime dependencies in the UI
• Guarantees: Page token encrypted at rest with AES-256-GCM, never returned to the browser, never in a URL or a log
• Status: 299 tests passing, CI green, MIT licensed, deployable in about five minutes
