Scrapebox Newb Question

Just got my SB license activated! Been poking around and did my first blast of links through some public proxies I found here on the forums.
After the blast was done, I used the checker to check the links...Out of 2000 links sent, it found like 6. Is that due to the proxies being over used and probably banned by Akismet or did I do something wrong?

In the bottom right of Scrapebox you will see "success" and "failed". After doing your blast it will show how many successful comments you did and how many failed. When you check for links right after a blast, the links it finds are auto approve blogs you commented on(that's why your links are showing up so soon). The rest of the successful comments are awaiting approval by the blog moderator.
