I've made a website which crawls files from all over the Internet and I feel like Google will ban me if I sent it sitemaps which contain all of these pages (1m+), because they contain only the file name/size/no of downloads and the download link(s).

I'm considering this thought because I've made another website like this in the past and Google banned me after one week with the reason: "spam", even it was not (maybe somebody falsely reported me?!).

Does someone have an idea about how to keep Google form banning my website? I've seen several other sites like mine and they don't get banned or... anything.

And also, should I sent the sitemap or wait until Google indexes every page as it finds them?

Thanks in advance :)
