[Bug] "Anything they said" not working?

so this person wrote this post, http://community.na.leagueoflegends.com/en/c/na-support/An0mpAjT-server-lag-and-disconnects

but when you go to their profile, http://community.na.leagueoflegends.com/en/player/NA/Shadow%20Seraph?content_type=all and click anything they said or any of the other options, nothing shows up

I've written on that post too, but when I check my profile I can't see any mention of me ever posting there.
