Can anyone including the admins tell me how to delete this plugin altogether from my site, for it has made my site look very ugly and I cannot find any option to delete the ugly '<' sign from my pages.
1. I tried disabling and deleting the plugin,
2. I searched for the adthis.php file but could not find.
3. I searched for functions associated with it, but it can be found nowhere.
In fact, it is behaving like a virus.
I searched the forum posts but from the admins' reply it appears they are behaving like irresponsible persons. My request to the Admins: Keep an option there to delete this foolish plugin altogether from the site.
