I am using this account. Today morning I have answered a question on Mathematics Stack Exchange. Suddenly my reputation dropped down. What is the reason for this issue? I am totally disappointed.
This week I was scoring nearly 500+ reputations. I lost everything.
Edit: I got a mail like below.
I'm writing in reference to your Mathematics Stack Exchange account:
Due to clear signs of falsified accounts being used to artificially inflate your reputation, your account has been temporarily suspended for 7 days.
It is not fair to other users of Mathematics Stack Exchange to allow users to gain reputation through sockpuppets.
The offending accounts have been removed and the votes invalidated. Please refrain from this behavior in the future.
