That's really bad and i also faced a Reputation drop when i was new that time i used a copyrighted image and forget to mention the source of the image and i got a massive downvote that decreased my reputation ranking from 43 to 9 and after that i do a lot of struggle and got back my ranking so don't worry just do hard work buddy :)
That's really very sad. :(
Thank you for inspiring me. Will build it all again through my hard work. (((Hugs)))
