What's everyone's thoughts about booting players during TB?

He was our lowest contributor anyways. As part of an alliance we aren't short on members, and our guild enforces strict TB participation as we're one of the "TB focus" guilds.

We have a hitlist, 2 strikes and you'll be demoted to a "TB lax" guild after TB. He messed up and cost us a star, and also didnt respond in game or in discord. He had a total of 5 strikes before we kicked him.
