Is this an ethical way of getting follow backlink from PR 7 website?

I was surprised to see this how people can get follow backlinks from a PR 7 website.

What do you think is this an ethical way of getting backlink where you modify the html "a" tag with style sheet not to display it or not to show a link.

just search for "style=display:none" from this website -->>

and there is one more way search for "style=color:#000;text-decoration:none;cursor:text;" in here -->>

What are you trying to explain ?

 

i tried the search but nothing was found, i dont get what you are trying to do here??

 

don't search with ", exclude it

 

Eventually, this site will be banned for this trick. I got such experience 3 years ago. Google became even smarter now.

 

is called spam and is just a comment
again, what is the point of this useless thread? is just comment spam..

 

I'm surprised you even have to ask.
