     Blackfriday flag: **`HTML_NOFOLLOW_LINKS`** <br>
     Purpose: `true` creates <s>external links</s> **absolute** links with `nofollow` being added to their `rel` attribute. Thereby crawlers are advised to not follow the link. While the `rel="nofollow"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links. One needs to make note of this if they use absolute links throughout, for internal links too (for example, by setting `canonifyURLs` to `true` or via `absURL`).

+    Purpose: `true` creates <s>external links</s> **absolute** links with `noreferrer` being added to their `rel` attribute. Thus when following the link no referrer information will be leaked. While the `rel="noreferrer"` attribute is typically used for external links, Blackfriday does that for _all_ absolute links.
