I agree with you, we have all apologized for making pun's about her weight, and that is understandably a personal attack, which we all agreed to not repeat. However, the moderator should be able to distinguish between a personal comment about someone's weight, and a very valid comment about how inappropriately someone dresses for a channel geared toward kids. When someone chooses to wear a costume to get a reaction, then it's completely fair to comment about that costume. I don't feel its fair to censor everyone who's reaction was not positive about that person's "shock costume" (as long as criticism is done professionally)
That all being said, this thread about about BQ's attack against another YouTuber, so we have all actually gotten off topic. The bigger issue with the entire BQ thing, is that her malicious attack on BrickSpy which is only the tip of the iceberg with her. Unfortunately she has influence over 140k subscribers, and countless others who watch her videos who have not subscribed.
I think we all agree that she should hold herself to a higher standard, and not attack a smaller YouTuber for simply reporting LEGO news. Apparently she has never heard the phrase "there is no such thing as bad publicity"...
