This report

High I got a report that riot deleted one of my posts and when I looked at it I got this ** While we do allow a number of topics that can be discussed about, there are some areas of discussion which are better left to other community platforms.**

What do you Mean left to other Community platforms!? It was a joke on the Memes and Games section, It was on the topic of League of Legends, What made it not viable on the boards Riot! would a rioter please come and explain? I am just confused.
