Right now every seller is clamming up tightly because of this most recent lawsuit against Amazon.
This forum is also going to get its share of critics/complaints/threats. It's been named in the lawsuit, a viral tweet from the lawyer who is suing Amazon (on behalf of the parents of two deceased teenagers) and this article.
With the attention garnered by this it's plausible to see more regulation. Potentially even outside of the US.
I don't think it'll get easier to source SN due to all of this.
