While I was checking @deepcrypto8 (Binance's deposit account for STEEM) I saw some users send SBD here. Binance only lists STEEM so SBDs sent here is definitely a mistake.

I quickly created a script to find out how many accounts did that mistake and how much SBDs sent so far.

```python
from beem.account import Account
from beem.amount import Amount


def main():
    binance_deposit_account = "deepcrypto8"
    acc = Account(binance_deposit_account)
    total_sbd_sent = 0
    senders = set()
    for transfer in acc.history(only_ops=["transfer"]):
        amount = Amount(transfer["amount"])
        if amount.asset == "STEEM":
            continue

        if transfer["from"] == binance_deposit_account:
            continue

        senders.add(transfer["from"])
        total_sbd_sent += amount.amount

    sender_count = len(senders)
    print(f"Total SBD sent: {total_sbd_sent}, sender count: {sender_count}")


if __name__ == '__main__':
    main()

```

Output:

```python
Total SBD sent: 6480.676000000005, sender count: 233
```

It's around 8000 US dollars.

Not sure @binance has a refund policy on this, but make sure you don't send any SBD to Binance.
