Hi I noticed this site is a memeber of the co-op: http://www.actiondays.co.uk/fac/ It took me some time to find the co-op ads on the homepage - right at the bottom of the page (no problem), but the font size was tiny to the point of unreadable (8px I think). Is displayed font size covered in the TOS? Is this against the spirit of the co-op or am I being pedantic?
It depends how you look at it - the coop network as far as I am concerned is here to provide us all with backlinks. Providing that the link is visible, does it really matter what the font size is?
I assumed the network was primarily an advert exchange system. The increase in IBLs being a nice side effect. 8px font size hardly counts as much of an advert.
