Although I really don't recommend it, you can opt out by adding this code to Special:Mypage/global.js

importArticles({   type: 'script',    articles: [        'u:dev:MediaWiki:AnnouncementsIgnore.js',    ] });

// Show all announcements except those from community central (ID 177) window.announcementsIgnore = { option: 'opt-in-all', exceptWikiIds: [ 177   ] };
