Sarada has a fascinating approach to dealing with spammers and self-promoters in her community.
She encourages them.
Every Friday, she lets those with relevant products/events/articles promote them in her community. It becomes something of an event that both promoters and members can look forward to. It lasts for one day. The rest of the week any such promotion is strictly banned.
It's not for every community, but it might be great for a few.
