Disappearing Comments

Anyone else notice their critical (but not offensive, toxic, or profane) comments getting deleted over the past few months? I thought I was crazy at first but I realized that when I post positively about something and return to check on whatever it was I posted to see if it got attention/replies I never have a problem. It's always there. However, whenever I post critically (but NOT offensive, toxic, or profane) my post will disappear entirely. Not always, but often. For example, today when the preseason introduction post on the main League page had been up for about two hours I posted a comment with a negative/critical comment (although it was more of a warning or prediction). Something along the lines of comparing the changes coming up in the preseason to how WoW died (more aptly described, fell from the most popular game in the world spot) when Cata was launched and introduced too many changes to the game. It was critical and negative but I wasn't rude, profane, or really toxic at all in my post. I'm now 100% sure it's gone and this isn't the first time this has happened to me. Agree or disagree with my points; I don't care. I just want to know if anyone else is noticing anything like this. Anyone?
