Its the whole phrase. It won't eliminate GM I can still see your post 

 Exacto, los GM de la gente los veo, hay que filtrar como spam la frase entera

 They're not actually blocking GM but the replies don't show up in the post and there's no actual conversation anywhere and no one to reply to or interact with! It's like a ghost reply. The notifications just look like this:  https://m.primal.net/KglV.png
