i'm also being plaged by psycheclone in a very short time i had 43 requests for 38 pages.
A few days ago it requested 51 pages in 1 hour (funny part is, my site only has 7 pages)
unfortunately i don't really understand how to block bots through the use of a htaccess file.
I have been trying to make one but only to find that no one could go on the site (not even me)
If there is anyone that would be willing to show me how to make a htaccess file so i can block
the ""badbots"" i would very grateful.
