MediaWiki:Spamprotectiontext

The text you wanted to publish was blocked by the spam filter. This is probably caused by a link to a forbidden external site.

follows two spam blacklists:
 * The local one maintained by our administrators at MediaWiki:Spam-blacklist
 * The global one at Wikimedia Meta-Wiki, maintained at Spam blacklist

Most likely the URL you put in is on the global blacklist. If you think it truly is not spam, please post a request at MediaWiki talk:Spam-whitelist so that can whitelist it.
