Until summer 2016, this pad has been maintained by @shiromarieke. I am no longer keeping an eye on it - feel free to take over.


This pad was previously https://pad.okfn.org/p/noncloudflare-torblocks

Moved because OKFN got cloudflared.
 
TorBlocker Hall of Shame Part I

This is a collection of websites that ban Tor exits, other than through Cloudflare
  (e.g. showing access denied pages, systematic timing out connections, ...).
  For cloudfare-related problems, please use https://pad.systemli.org/p/cloudflare-tor

See also
https://trac.torproject.org/projects/tor/wiki/org/doc/ListOfServicesBlockingTor
(the purpose of this pad is to provide a more dynamic list)

Feel free to add to the list. Ideally alphabetically sorted to minimize duplicates.

Please sample different exits before saying "works"

Freenode IRC servers (all exits, can result in auto kline) 

let's cluster them by similar responses

What about Akamai's

is that Tor specific?

Deutsche Bahn interrupts connection once you go to the ticket reservation page - the love story between railways and surveillance runs deep: the data collection and most of all the execrable CCTV infestation, even inside new trains. all of this would make a great headline: privacy gets thrown under the train as formerly free societies submit to total surveillance.</rant>

Discussion

TIP: to access sites that block tor completely, try using a web archiving service like https://archive.org/web/ (awesome and reliable, but honors robots.txt) or https://archive.is/ (relatively new, run by someone anonymous, does NOT honor robots.txt so it will work with more sites) Nice ... they are officially a museum and thus exempt from some copyright restrictions. Bwahaha ... What also works is startpage.com / ixquick.com "open via proxy" function for a great many pages, for reading it is great but external links get broken and posting is out of question. Or use Tor -> VPN or Tor -> open proxy if the need arises to truly Access a website.
Workaround for the impatient  Instead of looking at archived website versions use ixquick.com / startpage.com: They offer a proxy service for search results, apparently returning 403 for some websites. some websites return 403 to them, which is to be expected.
TIP2: Use another proxy between tor and reluctant websites. Usable proxies include https://proxy-nl.hide.me/ and https://www.vpnbook.com/webproxy. thx

What can a website do to become more tor friendly user friendly, really?
1. lift the stupid block
2. set up an onion
http://j7652k4sod2azfu6.onion/p/leurity, but it's conflating securty and protectionism. It is, in point of fact, neither. It's prevention of access by the unwashed masses, thus it is the elitism that only the middle class can hope for -- that which is not elite but bears its veneer. That veneer of the gated community. It is as protected as it is grey and faceless. The cookie cutter designs of the securitized state of exception we're all being tossed into.
*do you mind if we move these discussions to https://pad.systemli.org/p/torblocks-philosophy
or: at least be honest and change the HTTP code to 451 or 406 "Not Acceptable" coz that's what tor blocks are ...
