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.
It's impossible not to think that they are accounts with a single owner, but as long as we don't have more concrete evidence, we can't come to a conclusion. GazetaBitcoin, where are you? they are asking for merits from you, lol.
