How to hide a piece of code from a wordpress web page?

Without looking too closely, my best guess is that the footer text:


©2012 Америк дахь Монгол Оюутны Холбоо

is being processed through the the_content filter… something like:


echo apply_filters('the_content', $some_text);

Typically those social plugins add themselves automatically by hooking into the_content filter.
