Can me and my Brother can use single account of fiver
If you’re operating as a business and one entity, I believe so, but check Fiverr TOS to see if there’s anything against it.
sure, why not?
by the way, there is no way to know if there is only 1 or 100 people using the same account.
What you CAN’T do is to have multiple accounts to offer the same service.
Different account’s in the same IP can’t offer the same service. Or both accounts will be banned
Yes, you both can able to use it.
