Subdomain pass on manual penalty?

I have a few strong domains that were on whitelabels. These got hit with a manual penalty (not just mine,everybody using them). The reason was given as thin content(Despite 36,000 pages. Go figure!) I kind of understand why though as everybodys was pretty much the same,sometimes the whole of page 1 was the same WL. Since the penalty I have removed about 5 from the WL and put them through for manual reconsideration. I have added about 8 pages,each with between 600-1000 words. They all come back as still violating the guidelines.
I would like to save the domains as they are very strong but I dont want to waste a lot of time on them. Im wondering if I could make a sub domain of the main domain,eg test.mydomain.com so I can keep the domains strength.
I wouldn't be redirecting the root domain as due to a few tests I have done in the past Im pretty sure the penalty passes on.
What is everyone's thoughts on making a subdomain?

Penalty passes on no matter if you redirect with 301/302/307 but the thing is you'll have some time say, a couple of months to test the results before the sub-domain/new domain gets penalized.

The sub-domains will still get the same DA as if you're redirecting the root domain to a new domain. Nothing more or nothing less as google treats every sub-domain as a new domain/site.

As for the thin content and 36k pages, thin content simply means thin content. The total volume of pages doesn't effect the penalty but the uniqueness. Guess its is an e-commerce site. Are you sure all the 36k pages has 600-1000+ words unique content?

Since yours is hit with a manual penalty, I don't think you'll benefit much from redirecting but you shall give it a try. What does the violation say exactly?

Hmm this is what I thought.
It was an adult affiliate whitelabel and it was this that had the 36k pages. Mostly all the same thing for everybody using it. It was good while it lasted but I always suspected it would get canned at some point.
The violation just says thin content. The reconsideration reply just says "still violates guidelines". I took the white label off and decided to make it a blog instead so I put it on a wordpress and I added the 8 pages and the 600-1000 words on each page. It still came back as thin content so this is why im thinking of sub domains route.
This will have happened to every adult webmaster using the WL
Thanks for your advice though

After the first Panda update was rolled out, Hubpages lost a lot of traffic. But they recovered their lost traffic by switching to subdomains. Therefore, your idea might yield success.

Subdomaisn work
Atleast for me they worked everytime my homepage was penalised
