The way I see it is the rules exist to improve the experience of the community. They set guidelines to help us achieve that. The rules aren't the final source of truth though, the quality of the community is.
So, if you see something that breaks the rules and is pulling the community down in doing so, use the report function, and highlight it.
If it's breaking a rule, but not harming the community, then just let it fly.
I have no interest in enforcing rules for the sake of rules. I see them more as guidelines for fostering a better community, and that's the lens through which I moderate.
I'll generally remove posts without questions if someone reports them, but if they aren't bothering anyone enough to report it and I don't notice that they're in this community, then IMO, they're not doing much harm.
But if and when the community gets bigger, signal to noise ratio becomes a lot more important when it's harder to keep up with everything. But we can cross that bridge if and when we get to it IMO
