I used to be able to post without a problem in those markets. The last one I think was Jan/17.
Recently I decided to sell some pieces and was surprised I no longer had posting privileges on those markets. I followed the rules on the "posting privileges" link and sent an email 5 days ago. Still waiting for an answer or to regain the posting privileges.
Another strange thing is that I'm no longer able to find my previous posts when searching for my login ("pessoa00"). I can only find them by using some word/phrase I remember was included on the post, and then search for the date of the post.
Finally, I'm also unable to verify my email address. Tried it several times, but never received the verification email from network54. And no, it is not on my "Junk" box.
There, all my complaints in just one post!
