Protection from robots. Start.
That's what happened - not so long ago, evil robots turned against my blog . They started spamming my forms to send comments. In connection with this event, I was tormented by conflicting feelings for a while - on the one hand, spam caused disgust, but on the other hand, vanity made itself felt - I became more or less popular among robots :). Fortunately, the feeling of disgust overcame and I started to fight with robots.
Hanging a captcha, I had initially no desire. Therefore, I quickly generated a spamming feed. Its essence was to analyze the previous activity on the site. Namely - when sending a comment, she checked how long the page with the form was loaded. Oddly enough, the result was very good. About 90% of spam was eliminated with an acceptable delay of 30 seconds.
At the moment, this system works in my blog in parallel with the hidden field for entering spam identifiers. Those interested can check out just by leaving a comment on any of the topics within a minute after the page loads. (They say that sending comments podglyuchivaet me. I would be glad if you say in what browsers and under what operating systems)
I agree that such protection is far from ideal, because in the first place it is just elementary, and secondly it can interfere with ordinary users. But with these shortcomings, I can assume that they can protect not only from robots, but also from trolls. Plus you should not forget that this is only an experimental model.

At the moment I want to develop this system in the following areas:
In fact, it turns out a full-fledged analytical system for recording user movements around the site, integrated with the site protection from spam.
Surely I'm not the first who thought of this, but I don’t want to take ready-made solutions - I’m interested to write such a thing myself. However, if you used any analogs, I would like to hear about them. It is desirable with comments - what is good and what is bad in them.

At the moment I want to develop this system in the following areas:
- Include in the analysis all user movements on the site during this, and better, several past sessions.
- Add a check for links to traffic sources.
- Add additional tools to check robotization for doubtful users in the form of a Turing test aka captcha.
