Currently there is a gold card tournament in which I had previously registered.
In the first round I had to deal with @byzantinist, who is part of the Steemmonsters / Splinterlands team and almost always plays with multiple accounts, but Steemmonsters / Splinterlands had taken precautions and after I had set up and sent off the team they "disposed" me with the following message:
Oops, it looks like you don't have enough Resource Credits to transact on the Steem blockchain. Please contact us on Discord for help! Error: This account is not eligible for a delegation.
Do you really need to keep your opponents with such methods away so that you can collect the prizes with the team?
