While writing a script to check authorizations, I found that several old protocols I played with last year still had unlimited approvals hanging around...

Back then, I clicked "unlimited" for convenience, thinking I'd only use them for a few days. But the mainnet kept getting delayed, and I ended up farming a bunch of testnet points instead, leaving those zombie authorizations sitting there.

Revoking them is quite troublesome. The gas fees aren't high, but you have to deal with them one by one, and some even require finding the original page first. Anyway, I cleared half of them tonight, and I'll deal with the rest tomorrow.

To put it bluntly, everyone remembers to turn off the lights when going to sleep, but we forget to revoke on-chain authorizations.
