We've noticed a few opportunistic spammers creating what appear to be real posts, talking about our products the way genuine posters would. The posts usually contain links to whatever site they're pushing.
I'm interested if anybody has seen similar and has any tips? I'm concerned that marking the posts as spam might train the filter to route genuine posts out. Has anybody dealt with similar?
Yes, my previous community was facing the same problem. I started a topic on it here: https://community.khoros.com/t5/Khoros-Community-Discussions/Legit-posts-with-spam-links/td-p/549500
There may be some suggestions there that you can implement.
