This way, the owners of the websites that buddhi225 created will not be able to edit the link directly.
Of course if the have the source code, they will be able to edit anything, included the include(), but the link directly will not be able to be edited.

And buddhi225 can also add some type of license prohibiting modify the part of the include().
