Every user on my app will write 1 ordinal as a registering function for my app. It will not clog up the bitcoin blockchain and will not spam the bitcoin network. Gas fees will not go up because of my app, don't worry.
Bitcoin blockchain is not meant for data storage and Bitcoin is not a cloud storage. It is a payment system and the blockchain is ledger for monetary transactions. So it doesn't matter if it is 1 byte or 1 terabyte that you are injecting into the chain by using the exploit in the protocol, it is still abusive.
