I think that
this is the thread that began much of the attitudes towards what is considered blind and not blind amongst many list owners today.
For me, almost any linked text string that is part of a greater amount of text which forms an obvious ad block, is not blind - assuming the linked text isn't a complete falsehood.
As far as sponsor links with no supporting ad text or graphic banner are concerned; I like to see text which uses language surfers are accustomed to seeing as representing a paysite, such as Join and Instant Access. I want to see the site's name, but I don't demand that the link read "Click here for DownloadPass, where you'll get nothing for free". If the tour offers free samples pics or movies, I don't mind a text link that says "Go to DownloadPass for More Free Samples".
Though I understand what I refer to as "The Blind Link Revolution", I don't necessarily agree with the extremes of it. If you build cleans sites and aren't lying your ass off with your advertising text, I'm not going to bust your balls.
