Is there a timeline for re-opening the investment option to new users?
Currently we don't have plan to re-open investments anytime soon.
Follow up question, is it against the TOS to buy an account which can invest, and will support take adequate measures to prevent this account from being recovered by the original owner?
That's not allowed...from our TOS:
4.6. It is prohibited for players to sell, transfer and/or acquire accounts to/from other players.
