Today I got 25 reputation but I see it is reduced to 1976 as of yesterday. I was very eager to get to the 2000 milestone and I received it.
But after a while I could see I lost 25 reputation that I gained today. My answers are still there. Questions and answers are not removed and they are upvoted and answered also. Here is this link for the same.
What is the cause of this? I am not able to understand.
