I also encountered someone really stupid this by

I really want to complain about certain exchanges that come up with such disgusting operations for their events. If you can't afford to give out rewards, then just don't 🙄

Clearly, it's a normal account in use, and everything is fine while locking money in for the event. Once the event is over and it's time to claim rewards, they directly impose risk control on your account, claiming they suspect there’s a problem with it 🙄

I've seen many people on Twitter in the same situation; those who can claim rewards are doing so in batches, getting 50% on the 5th and 50% on the 14th. Reaching out to customer service yields no response. This exchange is really not even close to Binance; I've completely blacklisted this exchange. After all, you don't need me, a user under risk control.
