If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
This seems like just a mistake: The current LW terms of service (posted on April 23) forbid the use of automated scripts to export your posts or comments from the site.
This would include some of the tools listed on the site FAQ.
My understanding is that restrictions like this exist so that all scrapers / spiders / etc. can be banned or blocked at will if they become bothersome. If you put a restriction like "Don't use a spider, scraper, or other automated technology that interferes with the operation of the website" now you might have a fight on your hands over whether or not something actually "interfered" with the website.
