Also a representative here in forum form a high profile Huobi should at least be a copper member or a reputable account in forum which is totally opposite of the OP.
Buying a Copper Membership and get rights to post images are enough. If Huobi wants to have their announcement thread here, they can do it with a real representative, with a real newbie account.
If you hire a trusted member to post an announcement thread, you will have risk that you won't control that thread. The poster can turn to scammer, can be dead, can leave the forum for personal reason.
If you have a company and want to be here, let's create an authentic newbie account with a Copper Membership. It is not expensive for an exchange like Huobi or for any company.
