All tools of mine are 100% whitehat but final results depend on you. Frankly speaking, the software does not perform any questionable activities and has the only purpose - to automate your actions. For instance, it's 100% safe and allright to build new websites with content-rich pages, post comments on blogs, submit new bookmarks to social networking sites, comment on social media networks, and so on.
The software does the same and acts like a real human, therefore it's 100% whitehat. The only difference is that the software does it automatically to save your time and money.
However, it's possible to use the software for greyhat or blackhat purposes as well. For instance, if you manually post thousands of comments on blogs every day (though it's a time consuming and very difficult job), this activity may be considered as greyhat. If you configure the software to post thousands of comments automatically every day, it also may be considered as greyhat activity. As you see, there is no difference between actions performed by human or software. It just proves there is no risk using the software and you can be sure it's 100% whitehat.
