I believe so, as I use Clickbank and usually post those links in a links capsule. I know some discontinued products did result in the 'broken link' warning, I just can't remember if they appeared in yellow or if I worked it out by the fact there were no other yellow links on my hub so tested the ones in my capsule. I have a feeling they did appear in yellow though.
I have definitely seen non commercial links in a links capsule appear in yellow after a broken link warning.
You will see a warning icon on your 'accounts' page next to the specific hub. When you go to the hub in question, click 'edit', and the message will be highlighted in yellow, as will the broken link, or possible broken link. I recently had a warning for two possible broken links, but only one of them was.
I checked it again the next day to see if it was still broken, but the site was back up and it is fine.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
