Instagram caters to pedophiles and so do many other social media sites

I am very bothered by this. I follow someone named killallpedos666 on ig he exposes pedos today he exposed people who are selling cp on ig via bitcoin or pay pal etc. I reported the accounts well Instagram just messages me saying that they did not find anything on those accounts and that they do not go against their policies like wtf? They clearly say that they're selling cp which is illegal. All these social media sites cater to pedophiles it's so disgusting and it really pisses me off they're all in on it. They'll takedown the account of a person with an opinion but they won't take down a pedophile's account? I'm sick of this I am.thinking of deleting my ig I don't want to be part of a site who caters to pedos and defends them. F that disgusting sick world that we live in. Tumbler, Facebook, Reddit, etc. All have pedophile communities yet, no one does anything about them when you report them it's like America protects them so much. Sick shit I hate that so much.
