Todd McDonald explains an "unexpected side effect" from Google's Disavow Link tool. One comment suggests that bad-hat SEOs could buy and use links until they are caught and then ask Google to disavow them. McDonald believes the new tool might have "swung the door open" too much for the link manipulators. He tells us why SEOs that are too aggressive can capitalize on the short term while being even more able to regain footing in the long term. Before this tool, using paid links meant risking a lot. What does it mean now?
