Just a quick update about my sites since using Blackmind's services...
I'm just going into week 4 and have used it week 1 and 3 on my own high competition site and weeks 2 and now 4 bolstering some client web 2.0 properties.
My own site had got killed in the late September double update and till that point had been doing OK - it doesn't really rank for the big phrases because they are super competitive - like rediculously competitive but it was ranking nicely for lesser phrases and a ton of long tails.
After the big shakeup it ranked for nothing and traffic stopped altogether - like it had been deindexed, but it was all still there, just not showing for anything.
Now, just after two squirts of Blackmind's magic linkjuice it's getting good targeted traffic again - in fact traffic is up on its previous best. It's still not ranking for big terms, but again getting lots of long tail. In the three weeks since I started the service I've earned $900 in commission from the site, so its more than paid for itself - this is from a site that was dead in the water.
For the client site, it's a bit different - I'm going white-hat, so I'm using the service to strongly reinforce a few good web 2.0 properties in my tier one. I expect they'll start to pass on some good cleaned juice once the second set of links have been built.
I'd still be a little wary pointing the service directly at a real mega pride-and-joy site like a brand you've built or directly at a clients site, but for satellite sites and minor sites or for building fierce web 2.0's, or as I've found out for rescuing sites killed in Sept/Oct it's an awesome product and I'll keep using it as long as the service is being offered!
