Currently, the BioStars system works so that accepting/bookmarking your own answer does not add to your points. However, it does award you the Scholar trophy for creating an answer that has been accepted. This trophy adds to your points.
Should this be how it works? While there is a case to be made that you might legitimately find the answer and accept it, there are cases where this results in scores being way more than what they should be.
Should we make this a one-time trophy instead? Or maybe add a trophy to tackle self-accepts and make that one time, routing all self-accepts to that trophy instead? Which of these is more practical/makes more sense to the community?
If the community likes this, I can raise an issue on GitHub and look at working on this feature.
The trophies award points for "fun" factor mainly. It is nice to be appreciated in different ways. But it is true that these can be gamed. Now protecting this on all sides makes life a lot more complicated from the coding perspective. Features and protections don't come for free. Every single feature is a liability later when it needs to be maintained. Yes one should not get points for self accepting answers, but then perhaps it is more about making it easy to mine this data and find out who (if anyone) does that. I think it would be funny to find someone that tries to embellish their credentials this way - it is almost like a social experiment.
I will say also that one of the reasons that promotion to moderators is not automated (for example say based on reputation) is take out the incentive to game the system.
I understand that implementing and maintaining features is a huge effort, and the return of investment in this case is minimal. Is there any way of addressing someone we suspect of gaming the system? Reinstate as new user by an admin maybe?
We have to be careful and err on the side of caution. Something that looks like gaming the system may just be someone trying to be helpful. But there are clear cut cases:
Third category: User asks question, gets answers, answers own question and accepts it. I think we should look at this case by case.
I feel like I know someone who falls into this third category.
