FrontPage Guestbook, Board, Forms spam

The main raison for people spamming your FrontPage Guestbook, Forum/Board or forms is that the search engine Google, counts every "back link" (i.e. link pointing to these SPAM sites) as a positive vote. So if they can get a link to their site on your Guestbook, Google will interpret this as an "endorsement" of their site and give then additional "importance".

This spamming activity is especially common nowadays since they are thousands of automated scripts looking for FrontPage (or not, they will try to spam anything really...) guestbooks, boards, or forms to post SPAM links.

Apache Rotatelogs.exe for Windows Server

When using the Apache tool, rotatelogs.exe, you can see (using the task manager) multiple instances of rotatelogs.exe. Even when using it on just 1 web site!
To make this issue even more disastrous when restarting the Apache (httpd.exe), not all instances of rotatelog.exe are released.
Doing some research on the web it looks like this issue has been going on since years (Apache 1.3, 2.0 and now 2.2....).
Note: I've verified this issue with both Apache 2.0.55 and 2.2.0
