First of all, sorry for the typos but i am sleepy!
3 days is nothing but why dont you bookmark your website? You can create some accounts and bookmark the index page and some deeper links. It will be indexed.
Regarding crawling, google bots crawl everything unless they come across restrictions (robots.txt).
I would not say that your domain is banned for two reasons:
1. Three days is normal for a website not to be indexed
2. You bought it a year ago so even if it was banned at that time, it should be ok by now^^
