I assume you found them in the "mediawikis" table?

There are actually 3 wikis called "MediaWiki":

MariaDB [wikistats]> select id,name,statsurl from mediawikis where name= "MediaWiki";
+------+-----------+-------------------------------------------------+
| id   | name      | statsurl                                        |
+------+-----------+-------------------------------------------------+
|   64 | MediaWiki | http://reachwiki.net/api.php                    |
| 4347 | mediawiki | http://ariadne.cs.kuleuven.be/mediawiki/api.php |
| 9647 | MediaWiki | http://www.mediawiki.org/w/api.php              |
+------+-----------+-------------------------------------------------+

and one called "MetaWiki":

MariaDB [wikistats]> select id,name,statsurl from mediawikis where name= "MetaWiki";
+------+----------+-----------------------------------------+
| id   | name     | statsurl                                |
+------+----------+-----------------------------------------+
| 3681 | MetaWiki | http://biowikifarm.net/metawiki/api.php |
+------+----------+-----------------------------------------+

and 2 where the URL contains wikimedia.org

+------+-----------+----------------------------------------------+
| id   | name      | statsurl                                     |
+------+-----------+----------------------------------------------+
| 1209 | Wikimania | http://wikimania2006.wikimedia.org/w/api.php |
| 3459 | Wikitech  | http://wikitech.wikimedia.org/api.php        |

---

wikimania2006, wikitech and mediawiki.org are all 3 already in the "wmspecials" table http://wikistats.wmflabs.org/display.php?t=wx 

so just deleted them (id 1209,3459 and 9647) from mediawikis table and done.

(Yes, the URLs in "wmspecials" are broken in the display part, but that is another bug)
