Blocking users by IP at the server using .htaccess

Blocking users/ sites by referrer using .htaccess

Although, technically any time a server has to check and verify a query, it is taking additional time and the more queries it has to check & verify, it does increase the time involved. However, on any given day I have about 30 banned IPs & sites in our .htaccess files on various VPS accounts, but I can't notice any appreciable time difference. However, the servers these VPS accounts are located on are very fast...so I suspect, any noticeable time lag will vary on how big your .htaccess list is, and how fast your server itself is.

Oh, thank you very much but, I'll stick with the Vbulletin IP banning system for now. I have bookmarked those links though in case if I need them in the future. Thanks!
