Just a quick update. We are implementing SPAM hardening practices. Both at the front door as well as in our backyard. Since this a balancing act between good and bad, it may happen that your post gets routed into a moderation queue.
SPAMmers are a business. They are humans waiting for 'an order' to target a certain platform. They register and drop their dirty messages into our plate and get paid. It is a business and we intend to fight it with all means possible.
We will have to find out our way together. I'll keep you posted.
