Discord error 50034: Message too old to bulk delete

Bulk Delete Messages (POST /channels/{id}/messages/bulk-delete) only accepts messages younger than 14 days. If any ID in the messages array belongs to a message older than two weeks, Discord rejects the whole request with 50034; it does not partially apply. The endpoint also requires between 2 and 100 IDs and no duplicates, but those violations produce different errors.

Purge and cleanup commands hit this when they fetch the last N messages and pass them straight to bulk delete without checking age. In a quiet channel, the last 100 messages can easily span months. Message age is encoded in the snowflake, so you can compute it offline: (id >> 22) + 1420070400000 gives the Unix milliseconds timestamp.

{
  "message": "A message provided was too old to bulk delete",
  "code": 50034
}

Split every purge into two paths by age: bulk for the recent set, sequential for the rest, with a progress message because the sequential path is slow. Schedule recurring cleanups more often than every 14 days so bulk delete remains applicable.

The 14-day boundary is enforced against the snowflake timestamp, so a correct local filter eliminates the error entirely rather than merely reducing it. Bulk-delete bounds (2-100 IDs, no duplicates) are on the Discord limits page; individual deletes of the older remainder are subject to normal buckets, so pace them per http 429.
