yes, voluntarily creating a pile of radioactive utxos seems like a horrible idea to me.

Gleason has a whole section in the post about integrating Silent Payments into onchain zaps, but I don't see how that actually fixes anything -- I can imagine that the transaction sweeping a pile of small zaps into your stack is going to be disastrous for your privacy...Silent Payments or no.

Crap, I should have made a post about what happens with your anon set if you post notes from the same key that you transact on L1 with. Or well... Would be a short post. Haha.

optimism

Maybe what Gleason is describing is more like a payments network like Zelle or Venmo, where people connect their social identity to sending and receiving payments...but I think it's telling that none of those fiat apps have integrated a strong social media element.
