Hi Annie and thanks for letting us know about this bot.
I haven't seen it yet and have a few questions that would be great if you could answer them.
1. What's the User Agent String? 2. What's the IP range it operates from? 3. Does it honor robots.txt? 4. Is there a page on your site describing your bot? Normally there is a bot page, typically a link is provided in the User Agent string of the bot for webmasters to follow. I looked all over your site and couldn't find any reference.
Please let us know about these items at your convenience.
FWIW, their domain sub-hosts with BlueHosts, which presents no issue from the regulars here.
