So a little update.
Luckybird.io has been relaunched with new management.
I am currently exchanging emails with them and they might reimburse my balances that were left on the site when they disappeared.
I will post an update when I will hear back from them.
It's good to see the new management might be able to work something out with you but make sure that if they stipulate that you must remove any negative press about them that you let them know you will only edit your comments if they make whole on your accusation.
