No. I just restarted my alliance membership. So far, no ads like you're talking about. You're not alone though. Edit: I'll be damned. All of a sudden I'm seeing the ads. Only since my new membership.
I was just now going to say that I have never seen the ads and then, BOOM!, they're popping up all over the place including on member's posts. I'll bet that it's space aliens probing for life after the super bowl. MOO?
