Questions about Scrapebox, SEO and SERP

I would like to make a new site rank high in Google. The niche is fairly competitive and not exactly children-friendly so I'm not going to target heavily moderated blogs because most probably my comments won't be accepted no matter what. This is why I prepared a list with about 10000 unique auto-approve domains (random niches).

Can someone more experienced with Scrapebox than me reply to these questions please:

1. Should I comment:
A) with my homepage URL only?
B) with thousands of internal pages?

2. Should I use:
A) random name as anchor text?
B) main keywords (4-5 most important keywords) as anchor text?
C) as many as possible long-tail keywords as anchor text?

3. SEO-wise what is better:
A) spinned comment with no in-content links (there is a link in the Website field)?
B) spinned comment with in-content links (and no link in the Website field)?
C) spinned comment with in-content links (plus a link in the Website field)?

4. SEO-wise what is better:
A) blast 10000 auto-approved comments at once?
B) blast 1000 auto-approved comments / week?
C) blast as many auto-approved comments as possible (and keep doing it for as long as possible)?

I would love to hear your opinion. Especially if it's based on your own experience.
If you have something else to said, please go ahead!
Thanks in advance!

There are some great questions here. Firstly, I suspect forum members will need to know a little more before answering you:
- How old is the domain?
- How many keywords are you targeting and how many pages do you have relevant content on?
- Do you have any web 2.0 backlinks?
- What other link building methods are you using?

I recommend you try 2 or 3 keywords (on different pages), and see what the results are.

If you have many keywords - TEST, TEST, TEST - try different tactics for different pages and keywords and see what works best.

Good luck!

Thanks for your input, justin1234! Here we go:

1. The domain is brand new.
2. I target more than 500 keywords.
3. Yes.
4. So far social bookmarks and blog comments.

I hope that helps
