That and back in my WoW days it was "competitive" raiding with "creative use of game mechanics" - although those bans usually lasted for a few weeks or so most of the time.

I only remember coming across one of these myself, basically a boss fight where you could exploit pathing to take one of the enemies out of the encounter.

This was all just for boasting rights - being server first for a given boss fight with an undergeared raid group.

It was always a coin flip sometimes to understand if the strategy you came up with was going to get flagged by a DM or not. Usually for brand new fights they'd come warn you before an actual take-down they disapproved of, and you'd only get banned if you ignored the warning and continued. I can only assume Blizzard had alerts of some sort so in-game DMs would be notified when a guild started a give encounter.
