Link to the FFXI topic on this where it was brought up.
While I understand that ads are a main source of income for this website and pretty much every other website on the net, the prohibiting of talking about Adblock fore the Firefox browser is uncalled for. While ZAM may screen their ads to filter out gil selling/rmt adds or ads containing malicious code, not everyone does that.
Malicious codes in Ads are/or are becoming the number one way of infecting computers with viruses. It is very easy to make adds and slip them in fast before people can catch it. By not letting us communicate that there are ways or protecting your system from this kind of attack, you are opening up not just the FFXI community but every other community to malicious attack.
The FFXI community has had many run ins with this type of behavior and many people have lost game accounts/money because of it. I would ask that this policy be looked at again for the safety of your users.
