Are "blasters" a good marketing idea?

Does anyone of you have some experience with systems like ad blasters, search engine blasters, forums blasters and so on? I came across a site promoting tools like that, but i have no idea if this is working.

I'm in no way affiliated with this site and i'm not promoting it. Just wondering if some of you have tried systems/programs like these with any success...

Previously they used to work as I also used them but not now to that extent.

 

Really not the most useful types of tool.

 

It is not works for me. I have bad result with blaster

 

I would worry that these "ads" would be penalized by Google...

 

it did't work for me. I have been a member for few months but zero results

 

I dont use it....

 

due to the spammy nature of these all you will achieve are a lot of posts/links that annoy people and get deleted quickly. not a worthwhile investment.
