Why do random communities appear on my instance? (random-hero.com)

There have appeared hundreds of communities on my instance I have never searched. Where do they come from? Is it some spam attack? How do I prevent this, and how do I get rid of them?

Not sure how to check if they're bots or not, but I would enable captcha for registrations. Also that's where I was pointing at, other users might have searched for these communities. I also have many of them on my instance which I've never searched for, and I think that it's all from them. All it takes is for some random user to click on a community in a post and it's then added to your instances.

Not just that but some legit users will use a script to populate a ton of communities.
