Yesterday, my 100% likes videos started to get a few dislikes. I thought it's gonna happen eventually so I didn't mind it much but increased to 4 dislikes per videos overnight. Today, the dislike spammer is still going at it and it's now at 6 dislikes per video which is starting to affect the like:dislike ratio noticeably. I don't know who the person was and my youtube channel is nothing but like a diary of what's happening to games I play so I'm pretty sure I'm not attacking anyone. Since it's 2019, is there any new way to fix this kind of issue? It's really dirty how I can't know who the dislike spammer is and he/she's just harassing me non-stop w/o any consequences.
