The straw that broke the camel's back was Alex MacWilliams' vapourbots - Alex had withdrawn his previously given permission for Mark to use his designs on the FRA boards in any form last week, and in signing up for Crazy Bots 2.0 Mark entered two of the - now technically stolen - Team Targeted robots in his team, and then I understand he was somewhat dishonest in trying to cover up his tracks and lying about everything being 'sorted out' and 'okay' when it wasn't.
