Bitcoin Core source code provide short explanation about those configuration.

Quote from: https://github.com/bitcoin/bitcoin/blob/v28.0/share/examples/bitcoin.conf

Code:

# Relay and mine data carrier transactions (default: 1)
#datacarrier=1

# Relay transactions creating non-P2SH multisig outputs (default: 1)
#permitbaremultisig=1

AFAIK it means,
1. datacarrier=1 allows you broadcast transaction with OP_RETURN.
2. permitbaremultisig=1 allows you to broadcast multi-signature transaction which use P2MS (Pay to Multi Signature).

Those are default behavior of Bitcoin Core, so i don't understand why other node would determine it as a spam.

Good question, and I’m watching for any answers.
