One of the first things I wanted to do when I got here was to use AI to classify spam/ham and other things. I found this was extremely difficult to the lack of quality on almost every action. For example, votes, follows, reblogs, all cannot be trusted as they are heavily financially modivated and are not organic. Content uses many lanugages, is frequently spun/plagiarized (more so on Steem, less on Hive now days, but still happens).

I think on Hive is far more viable, but still difficult.

I am curious what specific questions you are looking to answer with AI. My initial goal was to automatically detect spam it just wasn't practical. I thought of a few other things like recommendation engine, rep algorithm replacement, and other things but due to the low quality metrics, it just wasn't viable.
