Black hat or no black hat; It's really sad that what almost everyone put some of the time they should be working more on their site is SEO. It's all about Google says this, Google says that, like Google is the only available search engine.
However, I wouldn't blame anyone for practicing Black hat SEO(which I wouldn't engage in) because it doesn't even matter what you have on your website on the short run(when SEO really matters). So, a little bit of unorthodox way to make the big factor "google search engine" see you properly could aid your long term goals.
Nevertheless, stay clear off 'Black Hat SEO', and do it the right way, with time and hard work your site will get there. Black Hat SEO works for a short time.
