if you post in public the transaction that you want to accelerate, you might be in trouble because if you don't accelerate it and will hope that nodes will forget your transaction soon, then there might come someone evil who will push nodes to broadcast your transaction and it will be unconfirmed till the day recommended fees match to your TX fees.
No need to post anything: the moment you broadcast a transaction, it's public knowledge. "Someone evil" can just be a node with very large mempool. But for most other nodes, 1 sat/vbyte is still under the purge limit, so they won't even remember it.
