I think Fiverr should employ a few psychologists to find out the reason behind a few people who: don’t watch samples, don’t read description & FAQs, don’t look what’s included in the package, don’t look at requirements and info listed there and then expect us to deliver a masterpiece. Their revision requests leave me paralyzed for minutes as they are far from what is offered in the gig. There are the people who will not read even on gunpoint.
Jokes apart Fiverr should add a feature called something like “seller’s terms” where sellers can list all his/her terms like I do not offer revisions in script etc. Fiverr may monitor these terms (just like they monitor gig page videos) to make sure they are fair. While placing an order, the client will see a line that says something like, “You agree to terms of the seller before you proceed”.
