If I run the same WiFi, two different computers on two different Fiverr accounts and I can give the same gig to 2 accounts.
You’re not allowed to have more than one account.
other account is not my personal account. We run the same WiFi 2 different accounts.
First you said it’s you running 2 accounts, now it’s suddenly “we”… Explain the situation to Customer Support and ask them for help and permission to run those 2 accounts. If you do it without their permission, both accounts could get permanently banned.
