All I can think reading all these posts is what a huge waste of time. People are being muted, banned, losing sleep and spending all of their time posting on the Etsy forums.
I know I keep saying this but its worth repeating. You will never be able to control what Etsy does. You can only control your reaction to what Etsy does. Instead of demanding Etsy change feedback to the old system (which is never going to happen) spend your time tweaking your Etsy shop or promoting your Etsy shop.
Negativity is like a cancer that just spreads and spreads and damages everything in its path. Do not let yourself get sucked in.
Spend your valuable time promoting your shop, stocking up on shipping supplies for holiday sales and creating new beautiful things to sell.
Etsy feedback is not going to make the huge difference people are predicting. I have always said no feedback is the best feedback and that is on Ebay or Etsy. I see people posting in the Etsy forum that they are sending letters with each package begging for feedback or telling buyers how to leave feedback. I for one hate when I make a purchase and get a letter begging for feedback. Don't do it! When you send letters like this you are actually making it easier for them to leave negative feedback. Because now you have forced them to really think about their feedback and what they are going to put. You have put the negativity in their head even though you didn't mean too. I got one of these letters with my last Ebay purchase. Because it begged so much I had to think it meant they must have a lot of poor feedback. So curiousity got the best of me and I went and looked. Yep they had some not so great feedback. Now if I had not got the begging feedback letter I would have never thought twice about it and never checked their feedback.
Time is too precious to waste being negative. Stay in the positive and get back to work!
