What's the format for proxies? IP

ort:user

ass or maybe IP : port : user : pass ?
I hope you don't steal proxy user and passwords with this software (although if you don't now, I gave you the idea now, but well, f**k it...)
EDIT: Anyway, I picked some random smaller autoapprove list (yesterday I was in the download frenzy mode and downloaded s***tloads of these lists) - Browsing through forum I've realized that these autoapprove lists are hammered heavily and tend to stop working pretty fast so I was trying to pickup those shared not more than 1-1.5 months ago.
Since I don't know the format to use to load up proxies with this software, I went with direct connection and 5 threads. I let it process 865 files, 238 were said to be successful and 5 autoapprove - I then went to check these autoapprove ones and none of them had a link to my site. I tried manually submitting to them, only 2 were successfull for manual submit and they were autoapprove, the other 3 not
Now, did I do something wrong here or something is wrong with the software - why did the software mark 5 of the 865 submissions as autoapprove when none of them had a backlink to my site prior to me trying to submit manually to them?
