Many wallets have recently received a transaction with advertisement for an inflation pool in the memo text. With a fee of 0.001 XLM, massively spamming the Stellar network seems to be pretty cheap. Is there any plan to prevent such behaviour in the future? The only thing I could find on the stellar website is this bit that mentions DOS protection:
There is a nominal fee, referred to as a base fee, associated with each operation in a transaction. The sender of the transaction incurs the fee.
The fee functions as a deterrent: Though nominal, it discourages users with malicious intentions from flooding the network (otherwise known as a DoS attack).
The base fee is currently set to .00001 XLM. The fee will increase if the system suspects an account is submitting transactions with the malicious intent to bring down the network.
How does this mechanism work? How is malicious intent being detected and what is the maximum fee a transaction could incur?
