I have exactly the same statistics. Ever since they announced the SS system, my score has remained stuck at 4. Before this change, I felt like I was in favor of Fiverr gods because I had an early payout option, even without Seller Plus, and an available cash advance option. I also had a pretty stable order flow without any promotion. Now, the situation is completely opposite. My gig seems dead, and I can't even use promotions to attract new buyers. I doubt CS or anybody else will help with anything. I am just hoping for a miracle at this point.
However, I'm tired of relying solely on Fiverr and being in constant fear of their unpredictable changes and completely untransparent, shady activities. I'm going to invest more time in creating my own online presence(website, portfolio, socials) to have something solid than counting on Fiverr roulette.
