Well, I think that it might be good to go to the google forum and share this. Maybe start a thread with a title like:
What's the effect of having massive short term links?
Or something like that, because I think you will get a better response, possibly from people who have been there / done that.
The google forum is at:
Personally, it sounds VERY risky. I am sure that seeing such a large fluctuation in inbound links is easily detectable and has to send off a huge red flag at google. Since just RECEIVING a huge number of inbound links has led to being penalized, wouldn't gaining and then LOSING a huge number of links be even more easily spotted and penalized?
Also, the TYPE of links sounds suspicious, too. If they are able to pull the links down, then they are obviously under the control of the SEO, right?
Well, I was just looking at a site the other day that had several DOZEN links that were under the control of the SEO. You know where that site is today? Banned from the google index.
So if only several dozen links that are under the control of the SEO can get you banned, then I am quite certain that having thousands or a million links will get you excommunicated from google pretty quickly.
Again, just my opinion.
