Unidentified robots.txt access

Any reason not to ban them?

Hi:

I see a lot of "whatevers" (bots probably, real humans, I doubt) reading my robots.txt... with no user agent.

Any reason not to just write a new rule in and just instantly ban anyone who reads robots.txt with no UA?

carfac,
Seem to recall you participating in Forum 11 (Search Engine Sipder ID?)

There are many threads and multiple criteria to both permit and deny blank UA's, however each webmaster must determine what is beneficial or detrimental to their own site (s).

A search [google.com]
