question about scrapebox! best effect

I am sorry posting it too quickly to a wrong section
I have read some threads that many people use scrapebox get a high aproved rate.what confused me is that what kind of comment they use to get a high aproved rate?

1. About the comment author name :filling with real people name or only your keyword? if use people's name ,does it give any help for ranking your website?
2. In the comment:use hyperlinks or just text? maybe use just text the aproved rate will be higher?but low effect for ranking?

3. How complex your comments are? I mean if you post comment to 10000 sites,even if you use many {|} in your comments ,but still many of them look same,so google will take it as low quailty comments and punish your site?

Hope someone can give me some idea,thanks!

1. Using names instead of keywords has a significantly higher approval rate. A link is a link, it helps.
2. Using URLs in your comments will almost always mark them as spam.
3. Search for a thread titled, "100 ultra spinned comments for you!" for some example lists.

Yeah i agree with JenniFranks except for the "a link is a link" part

Sure all links help but the search engines rely heavily on backlinks to measure
relevancy of a site.

So sure if you want your site to show up for Bruno Mars then leave a name comment

but if you are selling baseball bat paint then you want ppl searching for that term
to find your site. If not then your site is generally useless. just my opinion

Keyword result will have a smaller approval percentage but in the grand scheme of things
its not that big a deal because if the blogs owner really takes the time out to read the
blog they can notice a spam comment from a MILE away

"I really enjoyed this read. Will come back soon"
"the topic on which you write astounds me"

webmasters know that you didnt read the blog and this is an attempt to harvest
a link.
So either way it goes you lost a link anyway so you might as well use keywords in
the name field

thanks,I will take your two opinions as serious consideration
