The competitor site is also notorious for a lot of other things, but let’s not get into that either. You’re not going to change anything by posting on the forum–Customer Support is the only way to contact Fiverr, and you’ll likely get a canned response. The CEO of Fiverr had a Twitter Q&A where this question was asked multiple times to deafening silence. There is your answer.
You can always focus on the competitor site(s), for example. It should be noted that larger orders are very risky here on Fiverr, as a PP chargeback will see your money gone, even months after the work is complete. By batching up larger orders into smaller ones, you not only get your money quicker, you also offer yourself a little protection.
Instead of trying to seek change where there will be none, be the change you want to see! It’s just not going to happen, irrespective of your financial and personal situation. I suggest you look into the protests a couple of years back when the review system changed–TRS quit over that–but it stuck.
You can try, but you’re just wasting time–that’s just the way it is. See @torelles response above… er… below. Wherever it shows up. Same complaint, and business doesn’t care. You have to care and do what you need to do in order to get paid when you want. That’s harder than complaining on a forum, true, but that’s the simple truth of it all.
