Yeah, I got to front page of hacker news but I'm only getting 80 unique users per day on my website. Through there are now also 200 unique bots per day. (Where do all these internet bots come from?)
Yeah, I got a load of those bots too. Not sure if it's the same as yours but from what I can see in the system log, most appear to look for vulnerabilies by trying to access places like '/admin' or '/passwd'.
Thankfully a RewriteRule in .htaccess catches most of these although I can't help think if there's anything else I missed, security related. :\
