Penalized old domain, forbidden from google for 1 years, could ranking again?

I have a old domain A, penalized by google on 2013 June, then i 301 to a new domain B, after several month, also dropped, then 301 to another C, C ranking about 270 keywords for 1-2 month, then dropped to 150 keywords. so i delete it on google again, forbidden google robots, move to a new website, not use 301, now has been 1 month, only 3 small keywords appeared.

Domain
A--->B---->C ---->D
301 301 no 301

I let google no index all in google webmaster. Now A, B, C all forbidden google, no indexed in google

A, B, C all purchased several differece link building services on here, total spent more than thousands of dollars.

I have several questions

1. Now A has 1 keywords rank on 3 on bing, had no indexed in google for more than 1 year, if i let google index it again, what will happen?

2. Domain C, when i delete it from google on April 9th, it still has 150 keywords show on semrush, main keywords position is on 2-5th page, if let google re-index it, what will happen?

1 Google will probably not index it, or put it into the supplemental index, which is the same thing essentially.

2. Google will re-index it. Then it will be a website again.

If Google has tied this domain to your personal ID or to the ID of the person who spammed before you no matter what you do they'll make it very difficult for you to rank the site again if somehow you leak your ID to them(analytics,gmail,adsense,and so on).

Yes it could. One of my domains was banned for about 2.5 years, got unbanned last winter and crawls back to the tops since then. Currently on a second and third pages for many very profitable keywords, and for some little bit less profitable on the first. The niche is one of extremely competitive ones. The site was banned for backlinks (not just paid backlings, it was way worse), since then backlinks were mostly removed, I didn't change anything other with this site.
