Deb is correct on this, I am quite sure. The current Premium membership never offered ad-free. It offered less advertisement.
The problem here is more and more advertisements are added and premium members are not excluded from the new ads.
FAS, this is what was on offer in May 2007.
And this is what is on offer now.
For those who signed up for premium/lifetime under the May conditions, they are perfectly entitled to have the 50% less ads that they signed up for. Even if that means it is 50% less of 100 as that is the way it seems to be going around here.
For those signing up now, clearly there can be no complaint. It wasn't worth signing up for back then in my view, because MTF were always liable to move the goalposts. And it certainly wouldn't be worth it now for obvious reasons.
Also agree with Tangy about the "remove ads" link which is clearly misleading, as there are no removal of ads for premium memberships according to the current conditions. Sure, once you read (as you should), what is on offer then people should be able to figure that out for themselves. However, it is misleading nonetheless.
