 Please refer to this thread on the TOR Stack Exchange:
 https://tor.stackexchange.com/questions/19647/how-are-certain-websites-
 able-to-override-the-specific-exitnode-you-chose-and-c

 If I add the following to my torrc (and restart TOR):

 {{{
 MapAddress ayefiles.com
 ayefiles.com.719FD0FA327F3CCBCDA0D4EA74C15EA110338942.exit
 MapAddress duckduckgo.com
 duckduckgo.com.719FD0FA327F3CCBCDA0D4EA74C15EA110338942.exit
 }}}

 then I see that if I visit https://duckduckgo.com/, I'm correctly assigned
 to use exit node 185.220.100.252, which corresponds to the fingerptint.
 However, if I visit https://ayefiles.com, my exit node will NOT be
 185.220.100.252, but instead can be any exit node such as 176.9.53.58 or
 148.253.182.141, and will even change if I do a Ctrl+L to get a "New Tor
 circuit for this site" which should be a no-op for sites with MapAddress
 directives mapping them to a single exit node.

 How is ayefiles.com able to hack TOR and prevent it from applying the
 requested exit node?  Can we stop this from happening?

 Finally, if for some reason this is "expected behavior" (though I can't
 fathom how) please change this to a feature request to add a way to
 specify a single exit node in a similar way to MapAddress, except that
 can't be hacked.
