Banned for Forging?

I was just banned from Arena matchmaking for 35:33 for starting a forge game in Halo 5. Yesterday I was banned for 15:20 for exiting a forge game. I previously complained about the first incident in the “Why was I banned” thread, and it has happened again. Am I not allowed to use Forge mode anymore or something. I used to think that stories about this sort of thing were full of (CENSORED) but now I’m starting to think otherwise. I don’t want to sound like the fanboys and trolls who hate on 343I just because they’re not Bungie but… seriously 343? Forge Bans?! Please fix this… pretty please.
