Saw OP tokens in my wallet. Assumed it was a spam airdrop, but it looked legit so I investigated.

Turns out I was eligible for airdrop 1. Unclaimed tokens were distributed on Sep. 15. Checked the criteria; I fit the Active Ethereum/DAO voters category. 

Not a big airdrop fan, but followed the OP Stack channel anyway.

Ah I got these too. So it was actually just them distributing the tokens?

Yes, according to this (and the article I linked in the first comment):

"On September 15, 2023, any unclaimed OP from Airdrop 1 was sent directly to addresses eligible to claim. This means all OP from Airdrop 1 has been distributed."
