How to remove links from social bookmarking sites?

Hi guys, maybe you know a method how to remove backlinks from poor social bookmarking sites? Those site even don't have a contact form...

 

Block them on your side, by setting a new .htaccess directive.
I quickly searched a proper code, that should look more or less like this:

RewriteEngine on
# Options +FollowSymlinks
RewriteCond %{HTTP_REFERER} badsite\.com [NC,OR]
RewriteCond %{HTTP_REFERER} anotherbadsite\.com
RewriteRule .* - [F]

Code (markup):

Hope this helps

 

Does this will help to Avoid Google penalty?

 

I can say YES. This method has been used to block unwanted backlinks when you are unable to contact the webmaster asking for removals.

 

well, you penalized don't do it, Those back links seem un-natural, so they are most likely a bad thing; you should get a wide variety of links from various sources. You should try more Forum Posting and blog commenting.

 

Blog commenting also is not "safe".
