I'm building a small domain marketplace where I and a few friends want to sell a few of domain names. We plan to redirect (301?) each domain to a dedicated page in the marketplace website.
we wonder if google may interpret this as a malicious way to improve pagerank. is there a risk we get penalized or banned for that ?
What happen if we get bigger and gather thousands of domains redirections ?

which should pass no relevancy, or juice.
