Maybe it was not the vandalism but people trying to understand the 
functioning of the notes & comments system? Posting single letters does 
not look like a malicious vandalism.

It was still possible to give an anonymous visitor a possibility to 
delete his/her test notes (comments) by recording in the browser's 
cookie file an unique ID code of this visitor from say 32 digits and 
characters. And only if the ID code in the browser coincides, only then 
the "delete" button is displayed to the visitor.

Anyway it is not relevant anymore since there will be no more anonymous 
notes & comments.

Best regards,
