After submitting a Support request, I received the following today

"Dear users!
Please accept our sincere apologies for the delay. Verification on our platform for blocked users will be available next week. We will inform you personally when this procedure starts.
We have launched the main service on time and this one will be launched on time too. We hope you will stay with us, despite the inconvenience.
Thank you for your patience.

Looks like they are trying to solve the created issue.
