About scrapebox the comments which never show up

First of all hi to everybody ;
I am new on your comunity and i am reading everytime to learning something on this Forum. I have a question. I have scrapebox and i sent arround 2000 blog comment. When i check with linkchecker i see nothing found What is the problem ? Can somebody give me an idea.
By the way i am sorry for my poor english Please accept my apologizes

your list is not auto approve. FYI "posted success" on scrapebox means it submitted successfully not published (maybe blocked by spam blocker etc / need approval by admin first)

Thank you very much for your answer
