Remember there are two sides to this argument.

Pro core: allowing spam on the blockchain is good because (they still haven't explained)

Anti core counter argument;
allowing spam on the blockchain will make running a node more expensive.
Also allowing spam creates the potential for pedophiles to upload abuse material, which will make node running illegal.

ProCore counter argument:
Yeah well you just hate freedom of speech and you wanna censor our child porn!

🤔 I mean if the mention of child porn being a problem makes you get defensive well, that says a lot.
