referral spam is way, way up compared to where it use to be.
BTW, this is really handy if you like to work in shell:
[root@server ~]# tail -n N /path/to/domain.log |awk -F\" '{print $4}' | sort | uniq -c | sort -nr|grep -v domain.org |less
Replace the 'N' with the number of rows you want to see.
>Been looking at server logs lately and one thing I noticed...
Yandexbot has become a very frequent visitor compared to past years.
Possibly related to that: I did some searches on Yandex and, while I can't prove it, I just got the impression that Yandex has significantly expanded and improved it's English language index.
I am seeing a lot of fake traffic from primarily but not exclusively Russian sites. I am thinking it's to eventually end up in a lot of low level link/stats pages as a way of gaming link popularity.
