We always post the #HashTagGames Pascal case. Every word capitalized. We case them for a reason. First, and most importantly, for our vision impaired friends and Fedi-Neighbors who use screen readers. Finally, so the games are easy to read since the tags are sentences.
Instances should be getting them cased properly since the first introduction of the tag come from this account and is posted cased.
If your app or instance isn't pulling them up cased when you start typing and it suggests a tag, please let your admin or app developer know they should be pulling the case version of the tags from their database. It won't just help with our games, but all tags they pull up if posted in Pascal Case.
