Semi-Automated Forum and Blog Posting Tools

Hi all. I'm wondering if there's any automated-tool that suitable for Forum and Blog Posting.

My idea is like this,
I want the 'machine' / tools to help me search the forum/website/blog/social media's post that suitable for my post/comment and also help me create account and log in into that if it's necessary. But I want the 'human' / me to do the 'talking'.

So let say I want to boost my sites about A. I would like to the tools to filter the sites/blog/forum that currently discussing about A, create account and log in if it required, but I want to see the discussion, the article, the comment, etc, and I would like me to do the reply to the posts. I do not want the tools 'bombing' same phrase/sentence on all the posts. I want the tools (and me) to be more 'human' like, posting comments, etc, that relevant and unique for each discussion/articles/comment.

While reading the forum, I noticed some tools : (would not hurt if you have different recommendation though, I'll be happy to hear it)

RankerX
FCS Networker
Turboweb 2.0
Autofill Magic
Xrummer
AddMeFast Bot

Could someone give me your comment about the tools mentioned? Which would be most suitable or even the pros/cons or both pros&cons about the tools?

Also I would hugely appreciate if you could give me the characteristic of the software/tools (e.g. last updates of the tools, site limitations, the interface, price plan, etc.).
