Banning the troll was the right thing to do. And it was within the rules.

The header of the rules says:

These rules apply to the message board, boardmail, and any other messaging or communication function of this website. This includes board features such as Post of the Day, reactions icons, etc. Images posted by users (whether linked to from other sites or uploaded) are considered "posts" for the purposes of the rules.

The very first rule says to be generally supportive.  UFGM never once complied with this.  He consistently, thousands of times, was negative about BYU, our teams, and the Church via his reaction icons.  The rules say that an accumulation of negative posts (which include reaction icons) can result in moderator action.

BE (GENERALLY) SUPPORTIVE

With respect to the team, which includes all players current, former, and future (which could be any recruit), we expect all of our posters to remain positive and supportive. This does not mean that you can't express some constructive criticism that explores the weaknesses as well as strengths of our team. There is a big difference between "Player X sucks and is as slow as molasses" and "Player X needs some improvement particularly with his speed, but his strength and agility are outstanding". And there are a hundred shades of gray in-between. An accumulation of mildly negative posts with never (or hardly) a positive word said may result in action by the moderators.

Repeatedly using the reaction buttons to mock a user, without ever actually replying to their posts
