Ads in Sigs

[Omanes Alexandrapolites]

I've noticed the .Org becoming infested with ads recently. I've "AdBlocked" every single one I've come across - the annoying blinking ones were especially irritating.

In all honesty I'm not very happy about this. Are these ads necessary and where is all the money going? I thought the forum ad banners were for internal ads rather than ones from external third parties.

Edit: The image in the user in question's sig appears to be implemented by his choice rather than by an automated system. I doubt it has anything to do with the upper levels of management, although I do question whether it should be permitted and why he has placed it there.
