I've known so many open message board sites, social media sites, pretty much anything similar to facebook-twitter-reddit over the decades shut down due to "pedophilia" because one of its "users" posted child porn, and the moderators took a whole minute to delete it. In fact, if you look at my post history, I created my own message board, and sure enough, links to child porn sites were posted, and of course immediately deleted. Luckily the site was paid in bitcoin and it could not be traced back to me unless you somehow got some court order in a third world country to get the IP logs of the web domain and then the IP logs of the VPN I was using. And regardless I wasn't the one who posted it, and immediately deleted anything linking to it.

This is the exact same tactic with gun control. Start a shooting, say guns are bad and ban them. In this case, OPEN messaging sites with freedom of speech are bad because 1 deep stater pedo got through all of the security checks and spammed porn on there. It's not that hard to see their tactics in eliminating something they don't like.
