Polybius Bank IPO - recovery case scam?

Hi, 2017 i bought into the scam polybius bank.

just a few days ago i got a mail to register myself for potential refunds.

"polybiusrecovery"dotcom - but is this site legit? or is it just an idendity theft side? i am not sure.

i dont mind giving them my mail adress and amount of pltb ( i bought it with ethereum) tho.

not sure how it works, but if i register i shall give 1/3 of the refunded amount to the helpers. but do i even need them? so many questions
