I placed into TWC, he has 24h to explain himself.
After reviewing the whole situation with the Staff-team, we came to:
changed his T.O.S. from "You receive your deposit back", to "You won't receive your deposit back if you made profit from swapping, higher than your deposit".
He changed the T.O.S after @Takeoff joined.
announced his new T.O.S. over Skype, not Osbot.
@Takeoff never agreed to the new T.O.S.
has to refund @Takeoff the whole deposit, unless can provide proof that @Takeoff agreed to the new T.O.S which were changed after @Takeoff joined.
