Absolutely YES,
This is exactly what I was reporting to the Admins, months ago. Only registered users who bought an Arturia product should be allowed to write posts on this boards. All other forum members should be downgraded to a read only account! This is the only way to get rid of these spammers. Maybe Arturia should think about a kind of LIKE-button for them who have a read only account, so they can mark posts as useful/helpful.
Unregistered users should only be able to contact tech support if they have registration issues or questions about a product.
