Short version: discussion only.
- No service offers, packages, or "DM for pricing". The marketplace forums exist for that and require an approved seller application
- No case study that is really a funnel. If the write-up ends at a landing page, it is an advert
- Cite the data. "Google said" needs a link; "I tested" needs a sample size
- One thread per topic. If you are updating an old test, update the old thread
Asking for a recommendation is fine. Answering with your own service is not — point at somebody else's.
