Hi, I'm having last week alot of strange visitors on my site and if i see more details i see things like this => http://www.badkiller.kr/bbs/board.p.../www.xxxxx/content.php?pid=21339&sid=151544, I replaced urls with xxx but i'm receiving daily more than 30 from this visitors. Are this hackers or something ? I'm using the latest version of wordpress.
