"Spin - Free Blogs - Bookmarking - Directories - Article Sites - 30-50 articles per month..."
...do i still have a chance of get hit by Spam actions of Google?
There is absolutely no doubt about this. Everything you have said there is absolutely what should should NOT do when link building.
Link building needs to be handled carefully. You need to think about how you can invite links to your site, or produce content so good, that outreach will be met by authors who are happy to run with a link through to what you have produced.
Think about what you have to offer as a linkable asset. If you have nothing, then you must create something.
Amazing links will come from amazing content.
say a 500 word content for link building & spinning it 3 times & then using it for link building on social bookmarking sites, directory sites, etc. Will this be a good idea?
Absolutely not.
