voting rings

Okay so I know that voting rings exist for social media sites and I have tried pretty hard to find a way to get into some good one's but I cannot find any that are semi-underground. I'm really hesitant to use some of the more visible (usocial, etc.) one's due to not wanting to get my domains banned.

So those of you that are offering Digg frontpage services, etc. Do you utilize a formal or informal voting ring? If anybody that has the ability to vote up articles and soft launch them can give me a PM I would appreciate it. I can't seem to hunt any down.

I have tried autodigg and a few other sites but those don't seem to work very well.

As a power user on digg, the following is pretty much how it goes-
1. You vote all the other power users submissions.
2.You continue to do this until you either a)Get added as a friend by them b) Add them and they accept.
3. Either way they will digg every/most/some of your submissions.
4. You have to work out what works best. You cannot get on the front page by powerusers diggs alone. Its kind of 50/50. 50% powerusers diggs, 50% non friends diggs.

There are a few other ones that are quite frankly too long to go into. But these are the basics.

Okay, so build your accounts up and be a good friend to other power users... I am surprised a bit that people do that at least some of the time in return but I guess they have to vote/digg on SOMETHING to keep their accounts active and growing in value.
