Riot's Double Standard?

I been watching a lot of LCS games lately and older ones on YouTube. Why is it that the announcers that work for Riot can trash talk and make fun of people playing the game and laugh it off and yet if we used any of the same quotes,or or trash talk in a game we can lose our account? It seems to me this is a double standard on Riot's part that they allow their employees and LCS players do this but punish the rest of the community for doing it.

I mean you will delete a post if someone calls another person Trash but yet You can see in the video Riot is instigating it and at the very same time you will receive an email stating that you are not welcome back in the community because of the things you say. So basically if a Riot employee or LCS player does it for ratings it's ok but if we do it on the forums or in a game we are a horrible person and should be banned or our post deleted?

dou·ble stand·ard noun noun: double standard; plural noun: double standards

a rule or principle that is unfairly applied in different ways to different people or groups.

Not saying trash talk is a mature thing, but in competitive sports and game sometimes people do it for laughs or just having fun but yet I was to say " Hey ashe, you're trash" it's considered toxic, but if a LCS Player says it or Riot Employee agrees with it, it's just fun and games?

Or is it because we just say it in-game is the problem? If so Why do you ban people's account instead of just banning them from chat? If in-game chat is the issue isn't that where the punishment should be?

I mean I can get the same punished by joking around in chat and someone getting offended as a person who cheats, hacks or does something 10x worse. The punishment doesn't seem to fit the crime especially when you promote it on LCS.
