How to find all exchange transfers with a given memo with python

Earlier today was the scam-warning from @louis88 on people trying get STEEM with a fake Facebook page. The scammers promise to "return" STEEM for "verifying an identity" by sending STEEM to an exchange with a given memo.

Here's how to find out how many users were tricked by this with python:

from beem.account import Account
import sys

exchange = "deepcrypto8"  # replace as needed
memo = "105212323"  # replace as needed

a =  Account(exchange)
for op in a.history_reverse(only_ops=['transfer']):
    sys.stdout.write("%s\r"% (op['timestamp']))
    if memo in op['memo']:
        print(op)

In this case - luckily - nobody actually transferred any STEEM to that address. At least up to now. And it confirms that facebook all comments that claim to have received some STEEM back are fake as well...

For the less technical users

There is also https://steemworld.org which provides a transfer memo search function:

If the offer is too good to be true, always think twice...
