      this robot is quite nasty

      It somehow sniffs internet trafic and tries to access it.
      It even tries to pickup a copy of session-bound pages

      Not only nasty, it even intentionally ignores my robots.txt (which has not been updated for 1.5 yr) and directly crawls all pages explicitly disallowed in robots.txt.

      Thus I’m not nice to them as well.

      Rewritecond %{HTTP_USER_AGENT} "^Sogou"
      RewriteRule .* [L,R=301]

      This is implemented with firewall using packet rate limiting on ACK packets as well (yes, not SYN).
