NO, its not true. adsense doesn;t approve free hosted blogs anymore for applicants from certain countries but if you have a self hosted blog, you will still get approved
Its not true, adsense will assess your site and if it has good suitable content they will approve you whether it is a blog or a site or whatever.
Not it is not at all true. Adsense is infact now integrated with blogspot.com. If you have quality content anywhere, you can get adsense approved for even a free host like blogger!
Wrong, wrong wrong. A quality website (whether forum, blog or "home-made" site) will always get accepted if it follows the guidelines.
It is not true,you can get approved with a blog,all that matters is your site's importance vis a viz ontent and traffics
