The spam-blacklist doesn't filters a url that is not specified the protocol, but links properly MediaWiki. Taking http or https depending on whether the server is secure or not. This can be used to skip the filter. Example: odioalosmexicanos\.wordpress http://es.wikipedia.org/wiki/MediaWiki:Spam-blacklist http://es.wikipedia.org/w/index.php?action=edit&oldid=54363790
Confirmed. Urls without protocol can be used to avoid the Spam Blacklist.
