All the traffic spam that a website gets
I've written about referer spam before and sadly things haven't changed much. My site, as do many others, still gets hit on regular basis by referer spam bots in their never-ending quest to increase google ranking. Unfortunately, bandwidth is cheap and they don't appear to care that hitting my site is not going to help them - google does not index my statistics pages, so appearing there doesn't help anyone get a better pagerank.
I use mod_rewrite and what is now a forest of rules to deny them http access.
Worst offenders by far:
RewriteCond %{HTTP_REFERER} allinternal\.biz [OR]
RewriteCond %{HTTP_REFERER} djhits\.com [OR]
RewriteCond %{HTTP_REFERER} ass-traffic\.biz [OR]
RewriteCond %{HTTP_REFERER} drtushy\.biz [OR]
RewriteCond %{HTTP_REFERER} asstraffic\.biz
RewriteRule .* - [F,L]
Helpfully, this particular bot comes from one IP. Thanks guys, that's very thoughtful of you..
iptables -A INPUT -p tcp -s 69.31.79.2 -j REJECT
Of course, my iptables are full of these entries from flood-comment spammers already.. Most of these are proxies, but many appear to be hijacked machines on dsl and cable connections. People without firewalls suck.
