ooh that's a good move... but can you imagine making a little bot drainer account... even call it @botdrainer - setup only that account as a weird "whitelist" and refund it right away. The idea would be that the spammers would memo the account "buying promotions" over and over.
hahahahah it could work... it might not, but at least it would be hilarious.
I know, but those transfer would create unnecessary transactions for Smartsteem. I do like the idea of draining the funds, don't get me wrong!
