Managed path
If this community matters to your pipeline, scope it like a campaign.
Use math as one signal, not the whole strategy. The plan needs the surrounding communities, posting constraints, and the commercial context for your category.
The directory is informational. Live moderation behavior still decides what gets through.
Prefer the DIY path?
Signals is still the hands-on option for buying aged Reddit accounts or supporting a live post once you already know the execution plan.
