When I comment on blog, some are giving this message "Your comment is awaiting moderation." Is there any site list where my comment will appear instantly? or any techniques what i can follow? Thank you
If you do a Google search you might find some, but most likely not. There are many reasons for this: 1.) Sites constantly change their settings and more importantly 2) SEO companies and individuals in the field go through extensive efforts to find websites such as this (it is an arduous in part do to the reason earlier) , thus the lists are not publicly available and rather a provider charges a fee to place the comments. More importantly, comments that do not contain the nofollow tag are of the most value. A well written comment will likely end up approved, but if the link is a no follow it is unlikely to help much with your efforts.
If you are going to write a spammy comment that is totally unrelated to a post then I would strongly suggest you don't. Ok, fine, it might be quicker but it is pointless. Even if you leave 200 "Buy my stuff here www.bluewidgetsaregreat.com" type comments, the chances of them getting through moderation is next to nil. People are fed up of spam. What do do instead find a blog post you have expertise in read it carefully leave a thoughtful comment that adds to the conversation only make the link part of your name Alternatively, visit a blog you like and comment regularly, staying on topic. Eventually you might find that the writers begins to recognise you and might even offer you a guest post slot. Or, as another option, don't bother with too much blog commenting at all. It is outdated and although might be ok if you do stay relevant and on topic, it will be too much of a time sink to be viable long-term.
There are still plenty of auto approve blogs floating around. But most of these are low quality / spammed to death already. Scrapebox would make finding these a lot easier, though.
