I have a wpmu installation. Its working fine and all.
After long time, I just checked my web stats.
I see so many incoming links from so many domain's wp-signup.php pages.
some are
2u.blog.br/wp-signup.php?__CHBLOG_JUMP__=126&__CHBLOG_SKIP__=9444
blogs.sujets.ca/wp-signup.php
freeanimehosting.com/wp-signup.php
dragonflyeye.net/wp-signup.php
I did NOT release any plugins that works with wp-signup.php pages.
I don't see ads in their pages as well [may be they only show ads if google visitor somes?]
I got like more than 20 incoming links like this.
I believe its not going to damage my site rank in google. So what's profit for those sites? Or is there actually damage to my site?
