so sometimes i try to reply to a post cloudflare says i am blocked..
it says to email someone to get unblocked but i dont know who.
It might be because of a google chrome addon you are running, it seems that it is inflicting with the bitcointalk site in some form or shape, like you're trying to inject data into the site.
Maybe see if it still happens when you just use a clean browser, ( without any addons) ?
