Well, it says that I have 11 users on my instance. And I don't mind having them if they are not bots or communities crawlers. But it's hard for me to believe that 11 users could have searched so many communities in such a short period of time. Is there a way to check that they're legit users?
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.

There are a half-dozen scripts that do this automatically. It's entirely believable.
Someone else who is a registered user did. Pulling new communities is only possible if user is logged in on that instance.
Do you guys think I should enable captcha?
Uh yes... There are instances (mine included) that'll automatically defederate you if you have too many users with too few interactions, so better enable captcha if you're worried about bots.
How do I configure mine to do so? I mean automatic defederation
I made an announcement post for my community here and it has a GitHub link. I think, the repository has a python script that'll do it.
Thanks! I wonder if there's a script that purges communities that have 0 subscribers on instance
Unless you want the job of moderating your users you should close registration.
Barring that you should make sure email verification is enabled, captcha, and maybe even the questionnaire.
As an admin you can go to the applications icon, looks like a clipboard. Look at all, and see who's joined. If they're unwanted or bots, ban them.
Most of them from Lemmy.ml and Lemmy.world
