How to make the copyright secure

[veenuisthebest]

Hii..

I have seen mod authors usually place a copyright link at the footer of their mod page. Sometimes they are quite easily removable via the template.

I wanted to know how does Template Modification System achieves this thing, its really hard to make out how the copyright is placed, infact i just could not figure it out.

Any ideas how to achieve something similar?

thanks
