Fast approval Blogs and Forums

[martin2020]

I came across many posts saying that blogging and forum postings are that best way of generating more link juice to a website. But there are many blogs and forums that take time approving the comments or posts and finally we are left with a couple of approved ones (a complete waste of time and effort). So, does any one has any idea or trick by which we can find the blogs or forums that provide fast approval so that we can post or comment only on those...
