Hello,  
I would propose to migrate to [CrowdSec](https://www.crowdsec.net/blog/crowdsec-not-your-typical-fail2ban-clone) and replace [Fail2Ban](https://github.com/fail2ban/fail2ban).

CrowdSec is service that uses rules updated by the community.

Are there any plans for this?

Regards  
Thomas

It might be opensource but it’s a commercial product and sends data back to CrowdSec, so it doesn’t sound like a good default. It’s easy enough to install it yourself if you’d like

True, CrowdSec clients sends data back to a central server.  
However it seems like you didn’t understand the function of it.

I have no reason to believe that he doesn’t understand how it works. As I understand it, he just doesn’t think it should be the default, i.e. if it were to be included in MiaB at all, it should be optional, which I would be okay with.
