hi yes the Auto backlink Bomb is a decent tool - im the creator of it and its fully supported - its a nice peice of software for gaining profile links as it works with 6 forum platforms
Scrapebox is an M16 and Xrumer an AK47 ... the M16 will shoot fast and accurate, but every terrorist prefers the Kalashnikov. The M16 just clicks when you get a spec of dust in it, as Scrapebox does when I try to harvest 1mil+ links.
I hear scrapebox is pretty good. Also you can pay five dollars for some xrumer backlinks on fiverr and see if they end up giving your site any link juice.
Scrapebox is good for getting back links but you'll get spam complaints and ultimately added to Askimet. If I had it to do over, I would not buy it.
I found a working copy after a month of searching, i will only give the link to the first 10 people, they have to promise to not share it. pm me
I think Scrapebox is a great tool. It really depends on what you want because obviously Scrapebox doesn't compare to Xrumer but then again it's nowhere near the cost of Xrumer.
There's always some risks in using any tools in linkbuilding. Scrapebox is decent enough, but there are instances when it's becoming spammy and you'll automatically included to Askimet. That's not good at all.
