It's also good to consider the option of buying positive accounts to increase your chance of getting accepted and more payment.
Buying a positive accounts surely is the fastest way to do that but nope mate, you must consider the risks too. It's really not recommended and the account probably is a hacked account, especially a positive account and also once you get caught you buy an account, you will get a red trust for sure.
So why you are suggesting him a bad move bro. I too that it is allowed but not advisable as rules in the forum mentioned in the pinned message. To be a part of bounty campaign junior member account is enough bro. So if he creates the account here in the forum means itself he will be able to join in the bounty campaign and social media campaigns like FB and Twitter too.
