Maybe a strong deterrent isn't such a bad idea, think of all the pedos who used to come to 4chan posting their shit everywhere trying to get everyone into trouble.

I just want to internet in peace, I don't want to be swept up in this nightmare.

For a crazy motherfucker like a pedophile it doesn't matter, you can do whatever you want to them and they will eventually accept they deserve to be there and be ok with it, but for a normal person with hopes, dreams and ambitions it is a living death to be falsely accused.
Just stamp it out, purge the unclean.
