Weird Traffic

Subject: Weird Traffic

All,

  I have a leased server I use to host some websites and for the past
week I have been getting traffic warnings. The server has been
transferring > 1GB of data per day, which is unusually high,
especially since I moved my mail to Google Apps. I have noticed a
ridiculous amount of attempted proxying attemptes in my logs, but I do
not have mod proxy turned on. I suspect my server is on some list.  I
firewalled off a large number of subnets from China and my traffic
dropped for a few days, then this morning, 2735MB transferred in 24
hrs.

  As of right now, I am planning to blackhole all China traffic, since
thats where most of this is comming from, along with the occasional
traffic from France and other places in Eur. Is this common?  If so
are there any other remedies?
