I have a website built with WordPress and hosted on Bluehost servers. Given the fact that Awstats provides very useful information about the visits on my website, I use it for some time to track my web site statistics. The problem is that from time to time throughout the day I see too many IPs using a lot of bandwidth and significantly reduce the connection speed.

I’m sure there are some bad bots (most IPs are from China) that use my bandwith so I am looking for a way to block it using .httacces. I know several different ways in which I can block unwanted bots from being able to access my website, but now I am looking to block all IPs once.. To be more explicit, I want to block multiple User-Agent strings at once. Could someone here please give me a step by step instructions on how to do this?

Thanks a lot.
