He was very obvs an asshole before, granted.
But what do you want them to do? Sue him for damages after they kicked him? Maybe they should reconsider their contracts in the future and add clauses for "if it later becomes known you are the scum of the earth, this contracts is voided and you owe us the money + damages", but would this stand up? Without looking further into it, they did all they could do. But maybe I'm too lenient.
