Both are centralized systems. Also, it depends on the content, even on X. Many accounts are silenced or locked. Go tell the "xRp ArMy" what stingking pile of shit is their xrp coin and when many of them report your account, your account gets locked and you need to proove that you are not a bot or file a complain. I have filed numerous complains and I got my account unlocked every time. But now my VPN is blocked too, at which point I say, fuck it.
