For now, it doesn't sound that bad. It's a suspicion, they were not determined to be guilty. Moreover, it's about a token on their exchange, so it could be an honest mistake on their part with not doing their research. Or maybe it's indeed fraudulent activities, but the whole exchange cannot be blamed for them. Maybe some people were involved, and they will be convicted, but it's one of the biggest exchanges out there, and I don't think it's a bad exchange overall. Of course, you can never be too safe, so I would move money from Bithumb if I had any money there, but I don't think they'll pull an exit scam or something like that.
