There are a bunch of related scams that use Hive, where an account pretends to be part of a pool or exchange. The scam often involves a supposed form of arbitrage.
In the Hive.io Telegram group we are often getting victims coming in to ask how they can get their Hive "unfrozen". At this point they have already been scammed and we can't help beyond advising them not to transfer again.
The Hive chain is used in these scams and the accounts have a bunch of regular transfers that give the appearance of legitimacy.
I've started to make recurring transfers of 0.001 Hive with a warning message attached. Potential scam victims may be lucky enough to see the message and avoid getting scammed.
I am suggesting more people set up these recurring warnings when you identify a scam account. Even a thousand messages would only add up to 1 Hive, but could potentially save many people from being scammed. It would be a thankless job and you may never know if you helped someone. Yet the more messages these fraudulent accounts have in their transfer pages, the more likely their scam will fail. It's worth it not only to help people, but to mitigate the reputational damage these scams are already having on Hive.
