Today a guy sent me this

then he sent me an image in which someone else has logged in to my account and asking for money for solutions. i think someone just got my password of codeforces as i have used the same password on many places!! i dont know since when my solutions are being leaked (I highly regret for this) like this i request everyone too to change your password if u feel so.......

To be clear my theory is : these guys somehow have my CF account password so when i am giving contest and my solutions gets accepted they log in to my account now they can see my solutions which they sell on telegram and i don't get to know anything about this....... so i again request u all just to change your passwords thats it!!!!!
