Vine followers, gone afterwards?

[Jiggy]

So I had 39 followers. It shrank to 9 which means 30 where gone. What's weird is that they all had similar name styles like "Jon M. Go" and had the same location: "US". I also lost likes on my vines, one had 20 but now it has 2.

Now my followers seem to be normal. Thankyou for answering my question

There's not a question here. Someone probably used a bot on you then had them unfollow. You pretty much answered it yourself.
