Isn't it funny that when I click on "Remove advertisements", it opens a window informing me about the available subscriptions? It does lead me to believe that if I get a premium account, it will remove the ads.
Yes, and that's what they intend you to see. WTAW is also complaining about these ads (but they actually get more answers from admins). Apparently when it took you to the basketball forum, that was a mistake. Taking you to the subscription page is what's intended.
Maybe they are planning on getting rid of the ads for premium members now.
