How does this differ from scrapers hitting the blog directly?

Web pages aren’t digitally signed, aren’t necessarily indexed by search engines, and there are ways to block bots with things like captchas. You also have much more control over the UI. If your blog has comments, you can moderate them, for better or worse.

With a PDS, the replication happens first, before anyone reads it, and the UI is out of your control.

Maybe that’s okay, but people should understand the tradeoffs.

How can people control the comments about their blog post on Hacker News? I think my example is closer to what happen in PDS and App View.
