Trolls on YouTube?

So, let's kick it off:

I'm a small-time YouTuber, I enjoy it and post daily, etc, etc.

I was part of a community about 3-4 months ago when I left and they helped me gain about 20 subscribers. Anyway, since my leaving, they've trolled me ever so often and went on a rant and disliked my recent videos. I know it could be genuine dislikes but it's not, the channels are connected to people who are actually part of the community, so it is them. I have genuine dislikes, that's always going to happen but my recent videos all have 3 dislikes on, earlier, they had none. I just don't want this to ruin my channel.

My question, what can I do about this? If anything.

It just gets me down a bit and I move on but it's just disheartening really.

 

A troll isn't a troll if you don't care about.
Just forget them... It's 3 dislikes... That's nothing what so ever and even if they disliked your videos more, you're doing what you enjoy, which is making videos. Just keep at it and don't let them get to you.

 

You've got a point, thank you.

I say 3 dislikes, but it was worse when I was still part of the community, one video got about 16 dislikes and 20 likes. But still, thank you!
