I am giving users rewards for posting high quality topics on the forum. The metric I am using for high quality posts is likes from the community. However, this leaves the window open for users to collude and like each other’s posts to get more rewards.
I want to avoid that by checking what percentage of likes given by a user were concentrated to just one user? I am also using the daily likes given limit to restrict mass likes.
People must have faced this issue in their forums but I could not find a feature or a topic that addresses this issue. Can someone please share your experience or point me to an existing resource if I missed it?
