Not too long ago I set off a storm of comments when I called out the writer of nutch on the carpet claiming his creation was being used excessively and abusing my server all over the place.
I was told by the legions of nutchies out there that I sucked, was told to get off the public network, called everything from an idiot to a grumpy webmaster and worse. They all claimed that nutch was wonderful thing and made search engines that were beneficial and I should stop complaining, shut up and let them crawl.
Bullshit.
Being a patient man, I sat back and waited to collect enough data to show those nutchies that the usage of nutch is growing out of control and I really don't need 100+ unique IP addresses from everywhere from Turkey to Japan crawling my goddamn website.
Theoretically, if these 100 crawlers ask for my max of 40K+ pages each that's over 4 million pages served, assuming I let them have them in the first place, mostly for no purpose whatsoever.
Here's the list of the nutch plague seen on my site recently:124.32.246.36 NutchCVS/0.7.1 (Nutch; http://lucene.apache.org/nutch/bot.html; nutch-agent@lucene.apache.org)
So we cranked all these IPs thru the reverse DNS grinder just to see who was running all this nutch without changing the default crawler strings. There are some that failed reverse DNS but I'm too lazy today to bother with WHOIS'ing that list so anyone that feels compelled to dig deeper feel free to post the results as a comment.

I'll admit that a few of the nutches actually resulted in search engines showing up online but who uses these search engines? Best I can tell, none of the actual 400K visitors/month to my site that's being crawled use any of these so-called search engines and probably never will.
Here's the problem, and maybe I'm just using nutch as an example because it's so easy to spot this virulent trend with a single source, but the amount of things attempting [they didn't succeed] to crawl my site daily would easily become a significant portion of my daily traffic if I let them all in which is insane.
What happens when this trend reaches it's natural conclusion?
Where it's heading in that the crawlers will soon exceed the actual visitors in terms of daily pages downloaded as more and more search engines, aggregators, and spybots come online looking for more ways to sell a slice of the internet to an ever increasing bunch of specialized niche markets. Not to mention we're still dealing with all the scrapers, link checkers and down right dumb things like refererrer checkers abusing our bandwidth.
It's out of control and someone needs to put the breaks on this nonsense.
Someday soon crawlers, with the exception of the big search engines, will need to ask permission to get on just about any website of scale, and will need to make a compelling argument why they should be allowed to index the site. The day of just taking what you want and doing what you want with it will surely come screeching to a halt as the burden of all this bandwidth usage starts to hit the hosting companies and trickles down to the webmasters.
Maybe the webmasters will fight back first and take control before it's too late.
Here's hoping.
