I have purchased this specific twitter software and was VERY unhappy with it.
First the owner told me that it would come with proxy support, and when I bought it there was no proxy support.
Second, the owner had said there would be updated daily proxies to use with the software since at the time it was a few hundred dollars, and again that was a lie as well.
The software was VERY slow, and it took literally 2-4 hours to even get to the sending messages part of the software.
And when the software stopped working for me, I asked for a refund and the owner told me to get lost.
I'd recommend staying away from this particular software.
