Wait what? Since when are the node runners children?
The threat of childporn and malware is not a "think of the children"
It's a "making it more expensive and possibly illegal to run nodes will adversely affect node runners"
The child porn already exists, nobody is suggesting that core 30 will encourage people to hurt children.
The children in question have already been abused and the abuse material is already being circulated.
It's a threat to node runners and Bitcoin itself rather than a threat to children.
Although permanently hosting that kind of stuff may cause further trauma to those children that's not the actual concern here.
Anyway it doesn't matter because all that'll happen is that it'll create a fork and nobody will run the core 30 blockchain after it forks.
Bitcoin has already been through this before.
Same thing that happened last time will happen again
