Is There a Scam on Youtube?

The scam is all over youtube right now, everybody's channel. It's a bot doing it. There's really nothing i can do about it. I couldn't possibly comb through all my comment threads looking for this crap. If you're not sure, just click on the user name of the fake me who is replying to you. Click on that user name, it'll take you to their account, and you will see that they have no subscribers, no vidios. So it ain't me. Unfortunately, i'm sure some people have none the less, been taken by this scam, otherwise they wouldn't keep doing it. Other i suppose i could shut down the comments across
