-	~~An open proxy has been found on the IP address you attempted to connect to the DareNET IRC Network with ( {{#arg:ip}} ).~~ This ~~is not allowed by the proxy detection system we use to scan for open/insecure proxies.~~	+
-		+
-	~~==So why aren't they allowed?==~~	+
-		+
-	We have no problem with correctly configured proxies, they are sometimes the only way it is possible for someone to gain Internet access. However, when a proxy is misconfigured to allow access to anyone on the Internet (often called an open or insecure proxy) it can be used by anyone to "bounce" their connections through your system! This type of misconfigured proxy is an annoyance to the Internet community as a whole because they allow abusers to hide behind someone else's address. This can be abused by spammers to anonymously send unsolicited email ("spam"), to anonymously connect to a chat network, such as IRC, or access (and possibly abuse) web sites in an anonymous fashion.	+
-		+
-	~~==How does this affect IRC?==~~	+
-		+
-	If you have been on IRC for any length of time, you have probably seen an attack using open proxies at least once. Hundreds of clients will enter a channel, often with random nick names, and start sending large amounts of coloured channel and CTCP messages. Commonly they will leave and join the channel rapidly in order to cause more disruption.	+
-		+
-	Without completely locking up the channel, there is no effective way to stop the flood. Even if the channel is locked up, the floods of text can be sent to individual users and will usually be enough to disconnect them.	+
-		+
-	Most of these types of attacks use open proxies because open proxies are relatively easy to come by. Lists of them are readily available over the Internet. So this is why we do not allow them here on DareNET. If you have to use a proxy, it should be configured correctly.	+
-		+
-	~~== How can I fix it? ==~~	+
-		+
-	There are many different types of proxy software, in all cases you need to make sure that your proxy is configured to only allow the IP addresses within your own network access to it. A proxy which does not allow external access is considered secure. There are some types of proxy such as tor which have the express purpose of allowing anonymous access to services and as a result some IRC networks (but not all, such as DareNET) choose to competely deny access to IP addresses running tor exit nodes.	+
-		+
-	~~If you are not using any kind of proxy software then it is likely a trojan or virus~~ has ~~infected your system. We recommend you perform a full virus scan with up-to-date virus definitions. If you do not have a virus scanner try [http://free.grisoft.com/ AVG Anti-Virus Free].~~	+
-		+
-	If you are certain you do not have an open proxy or virus it is possible your IP address is on a list of previously compromised machines (known as a DNSBL). You can check this at [http://www.robtex.com/ip/{{#arg:ip}}.html robotex] and through our [http://www.darenet.org/~~gline gline lookup tool].
