A few months ago I noticed a lot of unnecessary extra activity from this bot so added it to my robots.txt using: Disallow: /
Recently, it has been on a mission, hitting my page dozens of times in a 48 hours period despite still having access to robots.txt, thereby ignoring its' rules, so it is now blocked it via .htaccess
Anyone else seen over-enthusiastic activity from this bot ?
