I have been trying to think of a response for this, as I am confused...
Are you asking how to convert your Black Hat Tatics to White Hat - Or How to Mask Black Hat to look White?
If Black Hat Tactics to White - Focus on putting out great content related to your niche, gaining social signals and building links in a manner that is not just for "Link Acquisition of Anchor Text" - Build a trusted prescece on the web. Focus on building informational long tail queries and building a following of people who think you or your product is interesting. (in very short)
If the latter....
I am not sure this is the right forum for that question, as most of us here spend our days doing things the "Hard' Way" (as described in your question) Due to this IS the longterm strategy - IMHO
Black Hat Tactics in General will never be consistent, cause the latest "fad" will always be rooted out as soon as the masses who follow the "Guru's" who always follow their leader, and latch on and abuse whatever loophole was discovered - Then Google will react - (Circle Ensues)
SEO is still marketing, and the focus always needs to be the consumers - So in general as a Marketing Tactic, black hat is not only un-ethical it is also a loosing strategy in the longrun (as the strategy must consistently change for fear of retribution)
But if you are really only 19 and in this for a few hundred bucks a week..... Then learning and testing to learn your limits as an SEO is important - Just as a suggestion jumping on the Black Hat Train is dangerous not only for you never know what tactic will next week be the new focus of Google's rath. But also consumers in general are becoming more "wise" to webspam and manipulative traffic, thus affecting not only your Search Engine trust, but also consumer trust (which is most important in my opinion)
The old adage "Work Smarter, Not Harder" is incorrect - You must work Smarter and Harder....
