I did here: Snip from Binance ToS:
Not even close to "causing trouble" or publishing information from customer service.
It feels to me like we need to determine what it is we are arguing here, it is taking far too many different directions.
I think there are at least two somewhat linked but different issues: user's account, and MONA fork/attack.
IMO at the very least Livecoin should unlock the OP's account regardless of "trouble" caused.
Beyond that there is a lot of precedent of how to properly handle forks and other issues, and it would be great if they choose a customer-friendly approach instead of expecting that coin developers (who don't really decide how many confirmations an exchange should wait for a deposit) compensate the losses of a private business. But I would begrudgingly admit that Livecoin can tell the customer to get lost (sell the coins at a loss, withdraw proceeds) and it wouldn't be too different from how most exchanges have treated their customers. Doesn't make it ethical or right, just a sad state of affairs, and probably not against the law in whatever backwater jurisdiction it operates in.
