You can't even imagine what crippled junk is browsing the Web those days. Undebugged would be a severe understatement. For example

Typically such requests are coming from servers with no DNS records
But for some reason some come from respectable sources such and Ba or Yandex. Both are prone to submitting incomplete requests, especially files with no extension:nslookup 180.76.6.20 Server: c.resolvers.level3.net Address: 4.2.2.3 *** c.resolvers.level3.net can't find 180.76.6.20: Non-existent domain

Sometimes requests from reputable bots are outright strange. Here are several from Google:
66.249.73.204 - - [02/May/2013:00:21:50 -0700] "GET /Skeptics/Political_skeptic/Fifth_column/Humor/index.shtml?id=184751176 HTTP/1.1" 403 82 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 66.249.73.204 - - [02/May/2013:07:57:36 -0700] "GET /Scripting/Perlorama/Functions/sprintf.shtml?node=print HTTP/1.1" 403 82 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 66.249.73.204 - - [02/May/2013:17:24:42 -0700] "GET /Internals/@ebt-raster;hf=0;pt=3543?filename=s1065x2.gif HTTP/1.1" 403 82 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 66.249.73.204 - - [02/May/2013:17:26:28 -0700] "GET /Internals/@ebt-raster;hf=0;pt=3543?filename=s1065x3.gif HTTP/1.1" 403 82 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"
In first two Google in its infinite wisdom used parameters such as "?id=184751176" or "?node=print". The last two look like a bug.
Some bots are definitely undebugged and can't traverse sites using relative links. For example they are unable to form correct absolute URL from relative reference.
Here is one example:
=== Hardware/Peripherals/Windows/Keyboard_and_mouse/AutoHotkey/index.shtml === +++ IP: 93.182.134.167 Referer: http://www.softpanorama.org/Windows/Keyboard_and_mouse/AutoHotkey/index.shtml === Hardware/Peripherals/Windows/Keyboard_and_mouse/keyboard_remapping.shtml === +++ IP: 93.182.134.167 Referer: http://www.softpanorama.org/Windows/Keyboard_and_mouse/keyboard_remapping.shtml === Hardware/Peripherals/Windows/Keyboard_and_mouse/keyboard_shortcuts.shtml === +++ IP: 93.182.134.167 Referer: http://www.softpanorama.org/Windows/Keyboard_and_mouse/keyboard_shortcuts.shtml === Hardware/Peripherals/Windows/Keyboard_and_mouse/keyloggers.shtml === +++ IP: 93.182.134.167 Referer: http://www.softpanorama.org/Windows/Keyboard_and_mouse/keyloggers.shtml === Hardware/Peripherals/Windows/Keyboard_and_mouse/mousekeys.shtml === +++ IP: 93.182.134.167 Referer: http://www.softpanorama.org/Windows/Keyboard_and_mouse/mousekeys.shtmlThe other problem is incomplete file names, where part of a long file name was eaten off because of limitation of the buffer for URL or some other bug.
There are also semi-debugged spiders that mangle URLs. One example that I recently encounter is something that identifies itself as 360Spider. It systematically deletes underscore from the URLs with predictable results.
182.118.22.230 - - [20/Aug/2012:07:10:43 -0700] "GET /Commercialunixes/AIX/security.shtml HTTP/1.1" 404 2 4859 "http://66.172.58.15/Commercialunixes/AIX/security.shtml" "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11; 360Spider" 182.118.22.227 - - [20/Aug/2012:07:10:43 -0700] "GET /DB/Oracle/connectiontooraclefromperlscripts.shtml H TTP/1.1" 404 24859 "http://66.172.58.15/DB/Oracle/connectiontooraclefromperlscripts.shtml" "Mozilla/5.0 ( Windows; U; Windows NT 5.1; zh-CN; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11; 360Spider" 182.118.22.227 - - [20/Aug/2012:07:10:44 -0700] "GET /Hardware/Peripherals/programmablekeyboards.shtml HT TP/1.1" 404 24859 "http://66.172.58.15/Hardware/Peripherals/programmablekeyboards.shtml" "Mozilla/5.0 (Wi ndows; U; Windows NT 5.1; zh-CN; rv:1.8.0.11) Gecko/20070312 Firefox/1.5.0.11; 360Spider"
But some bots operating under the cover of Google also suffer from this bug:
66.249.74.9 - - [17/Sep/2012:18:26:05 -0700] "GET /Net/Application.../DHCP/solaris_dhcp.shtml HTTP/1.1" 404 17950 "-" "Mediapartners-Google" 66.249.74.9 - - [17/Sep/2012:18:51:21 -0700] "GET /Social/Toxic HTTP/1.1" 404 17950 "-" "Mediapartners-Google" 66.249.74.9 - - [17/Sep/2012:18:51:22 -0700] "GET /Social/Toxic HTTP/1.1" 404 17950 "-" "Mediapartners-Google"
This media partner requests looks to me like Google bar replicating the HTTP request submitted by user reporting it to Google (one more reason to deinstall Google bar ;-)
