Can i bid on fiver by creating different account? Should i have to take permission for creating 2nd account?
No. Only 1 active account per person is allowed. Fiverr/CS isn’t going to allow >1 active account for the same person (if it’s a personal account).
From the terms of service:
Multiple Accounts - To prevent fraud and abuse, users are limited to one active account. Any additional account determined to be created to circumvent guidelines, promote competitive advantages, or mislead the Fiverr community will be disabled. Mass account creation may result in disabling of all related accounts. Note: any violations to Fiverr’s Terms of Service is cause for permanent suspension of all accounts.
