Answer:
If a question you answered got reported, then the moderator would delete it, and naturally the points u gained from that question would be taken away.
Sometimes it's not reported but a moderator stumble upon it and sees that the question is not academic, they'll delete it, and same result, u lose the points u gained from it.
Explanation:
This happened to me a lot, still does lma.o, that's why i try to stray away from questions that are not academic related or questions that violate their guidelines. So usually all the free points things will get deleted causing the points u gained from it to go away too.
Also cross ur fingers someone doesn't report this haha
