the very VERY least you could do, for stealing over $1000, is give him the worst one-star review ever on RM. most people dont read companyofmen, but they read and respond accordingly to bad reviews on RM.
also, in my humble opinion, he isnt worth $100 lol. but to each their own. sorry he stole your money! i dont know if its commonplace to give deposits but i never do it, especially because these guys know we dont have another (legal) recourse if they just bail.
