I know there have been a few threads about the disavow tool, but the purpose of this thread is exclusively a warning: Do NOT use it. Why? Because Google is trying to use us all against eachother. If we all use it, and 'snitch' on eachother, soon Google will have a giant library of backlinks that they see as low quality, thanks to all users of their tool. They don't even need to algorithmically detect anything anymore, it's simple, if enough people list backlinks in the disavow tool, then no one will be able to use those backlinks in the future, and possibly with enough reports that entire domain will be blacklisted. You may think you will benefit if you submit all your links to the disavow tool to get out of a penalty, but if everyone does this the long term effects will be that you can no longer build backlinks of your own, because they would all be blacklisted. Entire SEO services could be ruined, because you could get the service, disavow all their backlinks and bam, the entire backlink profile/footprint of that service is blacklisted. I have a couple sites hit by Penguin, am I going to disavow all their links to save a measly few sites? Hell no, I would rather they stay slapped than contribute to ruining things for myself and other SEOers as a whole. Essentially Google is using webmasters to create their own self-destruction. Maybe this warning would not be enough for dumbass WF members who are salivating at the prospect of taking their 50 cents a day adsense site out of a penalty, but I think BHW people have more sense.
