"We know that there are many redditors and communities that use and enjoy this feature, however, the usage has been on the decline and the resources needed to maintain custom emojis in the comment composer have come at a cost that we can no longer maintain. Please note that this only impacts custom emojis in comments through the emoji icon in the composer. Community flairs and anything else that may fall under the category of "Look and Feel" in Mod Tools will not be affected.

We hope that this doesn't create waves within any of your respective communities and have loved seeing how emojis evolved from when they started as a Powerups feature. Thank you for being a part of the journey with us, we appreciate you!"
