The real difference being that DaniWeb does NOT alter the context of the posting, it alters the formatting by adding the advertising links to certain keywords. The underlying message is not changed, there is no confusion over what the author has written. Forget about the whole 'I didn't endorse the advertising link' argument, that is spurious in this case.

What the ISP did in this case and what this posting is about, is change the context of the message as written by the author by adding a whole new block of text to it.

That is why is it an unnaceptable invasion of privacy, and that is why it is wrong.

If the context of the posting is an answer to a programming question, and words within the posting are converted into links to irrelevant products and services, the context of the post has been profoundly altered.

IntelliTXT does indeed add "whole new blocks of texts", sometimes several, inside of a post, completely unrelated to the context of the post.

But I'll let you have the last word, as we've reached the point where I've had my say and anything else would simply be repetitive. Also, now that blog conversations are uspide-down, it's incredibly difficult to follow who is saying what to whom.
