I've got some doubts, so I'll explain it on this post:
In my opinion I gave most of information in my answer. According to your suggestions in this topic the best way to improve my answer was to edit it, since Daissy already earned 1500 points. She could also add missing info as a comment.
If she did it as it is said here, she could be happy that she improved TibiaQA's database.
When she did it as she did - by adding new complete answer, she got additional 10 points for her answer, which is quite hard these days.
So this system absolutely doesn't encourage to improve database, but to SPAM with unnecessary content.
Times when several people actively participated in scoring points ended and it is much harder to get it when no one votes up. It's also harder and harder to come up with new questions, so now most of them seems to concern low-value knowledge. Therefore, a rational solution is, unfortunately, spamming, not correction of existing answers.
Going back the the question - I decided to edit my answer and add missing information to make it better, and now we've got two the same answers... and a mess. But from the point of user's view it was worth it, because of points.
