I'm in a couple weightlifting / home gym facebook groups and people routinely post links to groups that straight up sell growth hormone, steroids and other PEDs. It's annoying spam so I join the groups and report all the posts. For a while there, they would actually remove the groups / accounts but lately when I even get a response to the report it's always "this post / group didn't violate our community standards". Like bro, they're posting straight up price lists to controlled substances ಠ_ಠ
