  • Der Berliner Datenhack ist kein „unglücklicher Cybervorfall“. Wenn sich auch nur annähernd die behaupteten 5,7 bis 5,8 Terabyte bestätigen, reden wir über einen IT-Security-, Management- und möglicherweise sogar Staatssicherheits-Skandal er

#hack across platforms

every network with a public tag surface

Follow #hack straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

X (Twitter) ↗Instagram ↗TikTok ↗Facebook ↗LinkedIn ↗YouTube ↗Threads ↗Bluesky ↗Mastodon ↗Reddit ↗Pinterest ↗Tumblr ↗

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/hack
