Can't Make Jokes?

I got this message

after making this thread: http://boards.na.leagueoflegends.com/en/c/GD/JHMfEe9q-sweet-a-friend-request

I wasn't reporting anyone, I didn't have good intentions, I was making a joke about being disappointed about the friend request. This isn't harassing another player, because those aren't people, they are bots.

Someone explained to me the problem was I didn't censor the links the spammers sent me, but that isn't what the message said. If that's the actual reason and the message is messed up then I can understand that reasoning (although that creates the problem of faulty messages).
