Say crappy things about a brand online and I promise it won`t go in the marketing engine. What positive things are you saying publicly about a brand with hashtags that you also are trying to protect from being reused? Honestly though, I don't really advocate the way corporations do these things but I'm also in support of using my brain before posting content given the current circumstances.
