Hi, there are some problems with unregistered users:

Spam - you need to add some spam filter there (on this forum I use 6 independent functions to work against spam but I still get spam here )

Identification - registered users are great to identify but how to identify unregistered users: you can use IP but there are e.g. 100 users who have the same IP, you can use some special string (e.g. IP + user browsers + operating system, etc.) But what happens if somebody will change some of the criterium. Second if your site is visited by a lot of people you need to save thousands of strings to your database and thousands (sometime ten thousands or hundred thousands) strings need to be checked while every loading of the site and this will slow down the server a lot.

So I think, I cannot do such function as default. This needs to be customized and someone who will do such customization needs to know that his server is ready for such identification and spam
