It is proven! I am anonymousplanet on Keybase: https://keybase.io/anonymousplanet/sigchain#e2242037b9c5ad9befc95576abb90d3a4a4bb83553c91f5ee92442e655661f4c0f
@anonypla #Keybase is terrible for #security. Avoid it. https://dev.lemmy.ml/post/31190
@resist1984 In my case, I just use it for some linking to various resources for readers of my project. Not for ensuring my own security/anonymity/privacy. Nor do I recommend using it in my project. I mean I'm also posting on Twitter. I only ever used the app from a hardened sandboxed environment behind a Tor network Gateway as I don't trust it. But yeah since the Zoom takeover it's been unmaintained and I should consider not using it.
Linking social handles can also be done using https://keyoxide.org/ in a more… decentralized way.
