How come a lot of my websites show links from shady .ru porn and alike websites? Is that fake track backs or something? Seems like almost all websites I own have tons of traffic refferals from a variety of .ru websites. Also a few of my WP blogs have thousands of hits to wp-login.php, is there anyway to stop the bots from doing this? A plugin or something perhaps?
You have to block such website from admin section. There is no other way to stop. And install the some security modules such as akismet, cloudflare etc.
