8 Newbie accounts that have name ending with "@" (its not easy to come up with a more unique account names when you create them in bulk) did the quiz in the matter of ~3 hours. What are the chances for that to happen and not to have the same owner? 
I guess he liked the merit they received yesterday so they woke up another group of alt accounts.

I agree with you. I am a newbie though. I checked their eight accounts and found that five of them were registered in the month of October 2022. And three accounts were registered in June 2022. These accounts are cross-registered. Even if the accounts are not owned by a single owner. Maybe their family members.
