Hello, in the last week I tried multiple times pinning my products on Pinterest, but there’s no way to do it. Every time it doesn’t allow it as “it may be a source of spam”.
I even have my Spreadshop URL registered and verified on Pinterest.
Well, that’s it. Is there something that can be done?

As I said - this is not a Spreadshop issue.
I double checked with the colleague responsible and he confirmed it. Being banned from Pinterest can happen for a number of reasons. Sorry I can’t help you any better!
