user69083: I was quite busy for a few months and did not have any chance to check Arduino Stack Exchange and when I open today I have lost near about 120 points I don't know why and there is a message Serial Voting corrected. Is there any chance I can get back my lost reputation? Or do I need to earn them again?

user4143: Don't worry, you're not alone. We had a rogue user that caused some trouble, and their bad behaviour has been corrected. Those 120 points you had are gone I'm afraid. But don't worry, some people lost thousands of rep.
Keep writing great answers and I'm sure you'll soon enough earn them back.
