Yes you can flag alt accounts:
Can I also create a scammer flag for alt-accounts of the contract violator? Example: BetKing.io violated a contract, but BetKing Support, dean nolan and PocketRocketsCasino are his alt-accounts.
Yes, one of the victims can.That certainly covers it!
Thank you all.
Just wasn't sure if the other alts could only get a "type 1" flag.
