I capture things I find interesting at https://pinboard.in/u:andrewducker - I then post them automatically to various socials (BlueSky, Mastodon, Facebook, Threads, and X) and once a day to a link roundup post at https://andrewducker.dreamwidth.org/
Marciej mentioned the following when I noticed myself and asked what the cause was:
> Unfortunately you've run into a necessary anti-crawling measure that keeps the site from getting overwhelmed. About four months ago I started getting hammered by distributed crawlers from Chinese IPs, with no real way to block them short of blocking the entire IP range. Putting things behind a login is a stopgap while I try to figure out a more durable and friendly solution that makes it possible to have public-facing pages again.
Not that I think many people were looking at my Pinboard page directly. But still.
Interestingly it doesn't apply to the RSS feeds - you can still visit https://feeds.pinboard.in/rss/u:andrewducker/
Edit: I just checked and it's a single http call to get all bookmarks, very simple. Granted I 'only' have ~800 bookmarks, so it may get tricker with larger archives.
