An example situation for my above comment:
I currently have my (Waifu) Trading Card Game and am using Streamlabs to alert for high rarity cards being drawn and if a bunch of people feel like opening booster pavks, alerrs tend to happen at a rate of maybe 1 every 5 seconds, more if a person draws multiple high rarity card in a single pack. I would love to utilise the pinned message for this, but… i would be exceeding the rate limit instantly.
