I reviewed your post in question. The topic title mentions Blizzard in the title line implied in a way that is intended to call out the development team. This is probably why it was flagged by members of the community. The Overwatch Forum Posting Guidelines specifically states:
In most cases, most threads that break this rule often aren’t acted on. However I would encourage you to make sure you topic title and content is designed for constructive discussion about Overwatch. A more appropriate topic title would be “Why is double shields meta again? We need to nerf Sigma and Orisa!” or something like that. I hope this helps.
