dallas## Author Notes:
##
## For all practical purposes, open proxies allow people to spoof IP addresses. This can
## pose a problem when trying to ban someone or when trying make a complaint to an ISP.
## This MODification is an attempt to resolve that problem.
##
## At this point, you may be wondering - do open proxies have legitimate uses? Can this
## MODification block well intentioned users? To answer that, let's consider where open
## proxies typically come from - viruses. Those infected may be well intentioned.
## unfortunately, users in this situation are also considerable liabilities, since would-
## be hackers could use their computer to perform attacks on message boards and evade
## accountability / punishment.
##
## Alternative attempts to solve this problem using real-time proxy detection are much slower
## and much less accurate than this MODification due to the fact that they conduct their tests
## in serial rather than in parallel. As such, testing eight different ports requires
## 8*(connection delay) seconds, whereas this MODification only requires (connection delay)
## seconds.
##
## Attempts to solve this problem using DNS-based blackhole lists are flawed, as well. The
## following website elaborates:

##
## If, despite this flaw, you're still interested in using DNS-based blackhole lists, then
## you can try out another one of my MODifications - Block DNSBL Blacklisted Registrants:

##
## Moving on, if the MOD isn't working for you, then you may need to replace all occurances of
## gethostbyname($server_name) in admin/admin_proxy.php and includes/sub_proxy.php with
## '127.0.0.1'. The reason why this isn't what's in admin_proxy.php is that it doesn't work on virtual
## hosts (which are, incidently, more common than hosts that would benifit from the above).
##
## If you're interested in adapting this code to a more general proxy detector, you might
## find contrib/check.psd useful (it's basically a "check proxy" image - as opposed to just
## plain text).
##
## Also, I'd like to thank markus_petrux for helping to identify / fix a few bugs.
