Between them, these two have sucked in more than 6 times the busiest other crawler (which is google). They are responsible for 30% of my traffic this month.
I think I’ll ban them, once I’ve had the time to find out just who and what they are.
I have this high in my referrers too – http://www.miragorobot.com/scripts/mrinfo.asp. I mentioned them a while ago, and I emailed the company to ask what they were about. I never did get a reply, and I thought I’d banned them too. I’ll check.
And today I broke my bandwidth record yet again. Oh dear :)
I’ll post an updated wp help text later.
