Well the latest victim seems to be the vastly popular BMR judging by what they posted here. That's ironic they just gained a link!
Anyway - if you've been using these type of services regularly and relying on them what the heck is going to happen to your rankings now as you lose a ton of links?
I'm sure they'll find a way to move on and I don't believe the "backlinks are dead" rumours at least not until the big G says they are.
So what's can you move on to next?
Well perhaps it's not so much about what's next and more about not looking for a quick fix. Diversify traffic sources so you don't rely on just one which could collapse at any time.
Good content attracts natural links and there are plenty of websites that do very little backlinking themselves but it depends on the type of site you create.
Niche sites need to be set up the right way so you don't need mass link building campaigns all of the time and then you don't need to rely on large networks.
How do you think this could change things over the coming months and how could it affect how you create your sites?
