[Q] About SPIN CONTENT - SAFE ??

I dont follow any Google updates since last year and
now I want to come back into this field...


All things are done (website, content, design and so on).
Im in my way to make long term income site.
Now I wanna do backlinks on my site.
Since there are alot of G updates and I want to ask about:


SPIN articles are STILL good/safe for backlinking to main site?


I felt like a newbie since over a year im not doing anything related to IM...
My brain BLANK T-T
Hope you can answering my Question...
Afraid doing wrong and getting shutdown by G


I am grateful If anyone can share latest safe+good link building structure/properties
(i dont know if backlinking method still the same like past 2 years =.=')


Thanks,
Sry for bad grammar/eng
