Seems there are a lot of scams going around Hive recently. I guess with ai it will become all the more common. I'm not sure if you tried, but you may be able to regain control of your old account with https://claim.inleo.io/

As you say, their discord also has scammers impersonating support, the only offical way to get support is to use a ticket in their discord server i believe.

Creating a new account and retaining all your keys yourself is the safest way. Take care, and good luck building your account back up. Feel free to use #slothbuzz on future posts to earn some hive-engine $slothbuzz tokens and our manual curator will support your new adventures!
