8 out of 12 users are refused registration

Hi, on my site users need to be able to redeem a code and register here: https://mystery-solvers.com/register

but hardly anyone can register.

I know some of the users accounts are ‘pwnd’ according to haveibeenpwned.com. But many of the data breaches mentioned on haveibeenpwnd were in 2018 and 2019 and the passwords have been changed a long time ago. However, haveibeenpwnd is still saying ‘pwnd’ and if so, Cleantalk won’t let those users register.

What should I change to get users to be able to register? Now I have to manually mark each address ‘not spam’ in Cleantalk after the users contact me.

thanks
