Thanks for clarifying. And thanks for the note on the penalty -- I never did read the definitions section closely until now. So this would be a very limited strategy unless you could, as the original poster suggested, accomplish the difficult task of placing a tube w/o violating the zone.

Violating the zone would then only make sense if you're fairly certain you can break up a very high scoring logo. As noted previously, there doesn't appear to be a specific rule penalizing you for removal of another team's tube from its rack. Or placement of something else over it.

Depending on future GDC rulings, this would become a sportsmanship issue. On that I would suspect you will get quite a diverse opinion.
