Looks like you repeatedly run a robot against this site that performs the probe (which mean blatant disregard of previous notice).
That means that at any time after this notice you might be blocked for 90 days plus the number of probes detected.
Length of blocking also can be increased depending whether you committed other violations such as ignoring robots.txt, referer spam, frivolous POSTs, excessive 4xx errors or php probes to name a few.
For obnoxious offenders, who fail to stop this activity within a week from this notice we might try to contact their ISPs.
