[webkit-dev] Spam and indexing

The robots.txt file that we have on bugs.webkit.org currently allows search engines access to individual bug pages, but not to any bug lists. As a result, search engines and the Internet Archive only index bugs that were filed before robots.txt changes a few years ago, and bugs that are directly linked from webpages elsewhere. These bugs are where most spam content naturally ends up on.

This is quite wrong, as indexing just a subset of bugs is not beneficial to anyone other than spammers. So we can go in either direction:

1. Allow indexers to enumerate bugs, thus indexing all of them.

Seems reasonable that people should be able to find bugs using search engines. On the other hand, we'll need to do something to ensure that indexers don't destroy Bugzilla performance, and of course spammers will love having more flexibility.

2. Block indexing completely.

Seems like no one was bothered by lack of indexing on new bugs so far.


For reference, here is the current robots.txt content:

$ curl https://bugs.webkit.org/robots.txt
User-agent: *
Allow: /index.cgi
Allow: /show_bug.cgi
Disallow: /
Crawl-delay: 20
