Spam guestbook messages

[indeterminacy]

Last night I found two spam entries in my guestbook (at indeterminacy.blogspot.com). A google search of the names shows that they've been around. I don't know if these were mass entries. If they tried to hack the guestbooks, as was done last year, it seems not to have worked for them (fortunately). Just thought I'd let you know in case there's anything you can do about blocking these in the future. I'll leave the entries up in case you need to see them in the guestbook context:

I hope my input will help you to make the system better.

These are the spam entries:
