|This user-agent is an indication of a potential human visitor who is searching on keywords that your site is ranking for - the kind of person you want to encourage, not block. |
Actually, the invalid UA and invalid header are just the opposite, they are indicators of a fake, something you block to stop from getting scraped, hacked or worse.
If all this additional activity is indeed caused by pre-fetch, I'll be having a real big problem with the AVG toolbar real fast.
