ユーザーXが投稿Yでタグ付けされた場合、バッジを付与することは可能でしょうか？
例：
私が投稿を書きます：
「@UserXと@UserYの素晴らしい貢献に感謝します」
この特定の投稿でこれら2人のユーザーをタグ付けしたことで、バッジを付与するクエリは存在しますか？
The “First Mention” badge already exists; I’m not sure why you would want to encourage mentioning one person, that’d be very annoying for the target person.
If you’re self-hosted and can create badge SQL you could create SQL to make such a badge. Presumably you’d target it so that only you or staff would make a badge with @mentions–but that would mean that you could never @mention someone without giving them a badge.
Hard to imagine that you really want that.
Why can’t you just create a badge for them and award it manually? It seems a lot simpler, plus it avoids the issues Jeff and Jay mentioned above.
