You're confusing your blockchains, SV is the chain that is prioritizing storage. BCH is prioritizing cheap and fast transactions. Even Vitalik is expecting Ethereum data to get pruned
Limiting spammed comments appears to be enabling onchain social networks more than impinging upon them, I just linked a user that it prevented from spamming with faucet funds
Furthermore, this only serves to make the tx count for BCH inaccurate, and artificially inflates BSV's stats. They should move to SV if they want to fuck with a throwaway blockchain
Unlike BSV chain, I never uploaded any files to BCH chain. BCH chain is not for file storage. However, putting "message" on chain is allowed when OP_return was introduced.
