Yes, sqlite.org has protections in place to prevent bots from (recursively) iterating over all links in the web site. In my opinion, your tool should not try to follow external links. Any content of sqlite.org is **not** part of **your** website and should not be analyzed by your tool. It is perfectly fine to have hyperlinks to sqlite,org on your site, and your users are free to click them. But the tools should not do that. Just my two cents.
