I've seen a transaction with 24 ancestors in thee mempool, Is there a sensible use of this? Or is a kind of spam or something else?

It got mined on block 613101

Looking at the ancestor transactions this looks like someone is writing chunks of data to the chain.

The couple of transactions I looked at all have an OP_RETURN output and then send to bc1qraz56wyj28km560u2pyyml9dr3uaxv9sts67ct, chaining them together.

Looking at the OP_RETURN data, this could also be some kind of timestamping or another sort of anchoring as the data doesn't look random:

000c486100023...
000c487000029...
000c48740002e...
000c487500024...
000c48780002f...
000c487b0002a...
000c487e0002a...
000c48810002c...

It's hard to say. Maybe someone else has more insight into this.
