I just went through the ringer with scrapebox. I bought it, activated it, and had it licensed. However, it didn't run at all after download and setting it up. So I asked support for help. Got none. I tried again and again and again. Asking for help over and over with the only response an empty answer. Not helpful at all. I deleted it and reinstalled it. Still nothing, it didn't run. I would run my cursor over the buttons and the buttons should then light up, but they didn't it. I've got a great and powerful computer, so it should've ran. Nope. So, look out interested buyers. If you look around you will read many people complaining about scrapebox freezing. The thing about it is, if and when this happens to you and you need help from support expect nothing. All support is there for is to take your money and get you activated, and that is it.
What kind of footprints can it leave? It does post comments and it is software but the comment parts are handled by the bloging platform it post to not the software so the only footprints I can see are your comments,usernames and websites. the rest is standard footprints and it would be the same as doing it by hand. Worried about footprints use the best spinner and come up with about 50k or so comments and there you go you can have about 50k without leaving a comment footprint what so ever. Of coarse you will still leave username and website footprint. Then again if you do not leave that footprint why do commenting at all?
