One of the rules of participating Crypto.Games Signature Campaign:
4. Only one account per person is allowed. Alt accounts will be banned from campaign without getting paid during payday. Leave the campaign if any of your previous alt accounts were banned!
And COINS.GAME Signature Campaign
You, a person, are not allowed to enroll with more than one account.
It's just a rule relevant for each campaign, so if he enrolled both of his accounts in the same campaign, he would violate the rule and DT could tag him. However, since he just enrolled 1 Account for
each campaign, he's not violating the rule. But could be interesting to follow (or to track) if he enrolled both Accounts in the same campaign in the past. If so, a negative Tag for Signature campaign abuse would be appropriate.
