Blocks were registered permanently. An IP block is a claim about who is currently behind an address, and that goes stale: VPS addresses are recycled between customers constantly, and now that the /24 ceiling means most blocks cover a single address, a permanent block increasingly punishes whoever gets that address next rather than the actor we saw. 24h is long enough to break a signup run -- the abuse arrives in bursts, not as a steady trickle -- and short enough that the blocklist stays a live picture rather than something that only ever grows. Mastodon expires these itself and reconcile_blocks already reads an elapsed expires_at as "gone", so expired blocks leave /api/blocks unaided. The one piece that needed adding is an expiry on our own dedup record: reconcile runs hourly, so between a block lapsing and the next pass, reputation_block_ installed would otherwise claim a block Mastodon had already dropped and skip re-installing it. expires_in is omitted rather than sent as 0 when the expiry is switched off. Email domain blocks have no expiry in Mastodon and are untouched.
