GeekShed maintains a spamfilter of URLs and phrases that are blocked network wide. Most of the entries on the list got there because someone was spamming the information on the network. Some entries are added because they link to malware, porn, or another kind of less than desirable site.

What happens when someone triggers the spamfilter in a channel?

If you make a statement or action in a channel that includes a URL or phrase on the spamfilter list, your text will be blocked completely. No one in the channel will see what you said (though you will probably see it). Immediately after the text, you’ll see one of these messages:

   * Message blocked: Spamfilter match. Do NOT attempt to 
     get around this filter. If you think it is an error, 
     tell us in #help 

   * Message blocked: Spam URL

What happens when someone triggers the spamfilter in a private message?

Your text will also be blocked completely if you send a private message (PM) that includes a URL or phrase on the spamfilter list. The person you were trying to message will not see the message at all and will not know you tried to send a PM.

You’ll see this message in your status window or a query window, with <nick> replaced with the person you were sending the message:

   * Message to <nick> blocked: Spamfilter match. Do NOT  
     attempt to get around this filter. If you think it is  
     an error, tell us in #help

What happens when someone triggers the spamfilter in a channel topic?

Your topic will not be set if you try to include text that is on the spamfilter list. Instead, you’ll see this message in your status window or in the channel:

   * Setting of topic on #channel to that text is blocked: 
     Spamfilter match. Do NOT attempt to get around this 
     filter. If you think it is an error, tell us in #help

What is the punishment for triggering the spamfilter?

If you accidentally trigger the spamfilter, generally nothing happens. Just take note of the warning, and do not attempt to get around the filter or continue posting the blocked text.

If you continue to trigger the spamfilter, you may be banned from the network.

Does anyone else know when someone triggers the spamfilter?

Network staff will see a message that says you triggered the spamfilter. No one else will know (unless you tell them).

Can I see the list of words, phrases, and URLs on the spamfilter list?

No, we don’t provide a list to avoid abuse or misuse of the information. Do you honestly think we’d want to post a list of malware, porn, and undesirable sites?

Can someone add URLs or phrases to the spamfilter list for their channel?

Not exactly. Only network staff can add text to the GeekShed spamfilter. However, you can use the extended ban type ~T to block specific phrases from your channel, essentially, creating your own private spamfilter.
