Hello sellers I wish a good day for you all, this topic related to the scammers in the form of buyers, who will search new sellers gigs and will send them message to do no pay work before placing an order, because they want to test your ability and if they pass you then you will have more work from them, this is totally insane. If a seller following all term of Fiverr then buyer also should follow and place an order to seller if the job is small or complicated does not matter. I will suggest all sellers do not work without placing an order. You will get scam and waste your time.
Wishing best for you all
