We have a simple user rating system to help with trustworthiness of user transactions on the marketplace.
On every users profile page you can vote up or down your experience with a user.
You just vote the user in general, not single transactions. It does not matter if you are the seller or buyer.
The accumulated votes will be displayed on offers and in the user profile.
Send Limits in the Messenger
A spammer tried to send thousands of automated messages to users and partly succeeded (sorry!).
We now have a rate limit to prevent that in the future. Standard users can only send three messages per hour. Unicorns can send unlimited messages.
