I tried seo-smart-links plugin and it linked all my posts to tags/categories and other posts. This looks stuffing and spamming to me so I uninstalled this plugin. Now the links are still there but the plugin author said links are created on the fly so they will be removed after uninstallation but it didn't.
Kindly let me know how can I revert it and remove those links created by this plugin. You can have a look at technostall.com to see the situation.
