I've been encouraging Etsy sellers to joint this protest. http://www.protesty.com because I think that you should be able to stand up for what you believe is right. But I've recently read a blog post that I think you all should read. I guess with honor, there comes sacrifice and I feel that I should warn you.
Please take a few minutes of your time to read The Hands of Handcrafted and How I was Expelled From Etsy
You will be shocked and amazed because this honest seller had her shop shut down because Etsy accused her of using her "public areas" of her account "to demonstrate or discuss disputes with others or with Etsy". In other words, that she might have protested something. Decide for yourself if her words were inappropriate.
My fear is that if you join the protest that Etsy might retaliate. If you join the protest and put your shop on vacation on May 10, please do not leave a message on your shop as to why you are closed unless you are willing to loose your business there. I realize that many of you are so angry that you don't care today, but realize that Etsy is the best venue for vintage and handmade. It' has taken my daughter and myself a solid year to get back on our feet again after our Etsy disaster.
I'd say be brave and stand up to them. But be cautious about it. Don't take unnecessary risk unless you are willing to start from scratch. Good luck to you all.
