The functions of the boards are unclear

A fell minutes ago I came up with a idea to get place the Rift Scuttler (the new monster for season 5) on the Twisted Treeline map. Since it had todo with ballance I decide to place it on the "Gameplay & Balance" board. But suddenly I recieved this report:

We have removed your content due to a violation of the following board rule: Adhere to Board Guidelines

You've created some content for the boards. Thank you!!

Don't worry; you're not in trouble! This is just a heads up, and a reminder to become more familiar with the Guidelines for each board so you can ensure your content is appropriate. If we don't keep things organized, the boards will become less useful and a lot more cluttered.

I can understand the content might suit better on the "Maps & Modes" after thinking about it again. But why didn't they replace it. How I feel after reading this report is that they didn't had no clue about their own content. Probaly because the Rift Scuttler just recieved this name recently. Previsouly he was named Scuttle Crab.

So where does this post belong?
