Increase Scrapebox Speed?

I want to start using scrapebox to sell backlinks, however its going sooo slow. right now im getting like 16 successes every minute. This isnt going to work for a service or itll take all day. What are some ways to speed this up?

Right now im getting about a 10% approval rate, so if I had a list that had a much higher success rate that would speed stuff up.

Right now im using 4 private proxies. if I were to use more private proxies would that speed it up as well?

wheres a good place to get a high approval rate list?

Thanks.

10% approval rate with private proxies mean that you're using poor lists.

Fresher lists will get you better approval rates.

There is a thread *somewhere* which offers help on tweaking your system settings to get more speed from scrapebox but I haven't had time to try it yet.

If it helps, I've been running on a pc rather than a VPN, and been using hidemyass for proxies - I've got the paid subscription, but it only costs $11.52 per month and less if you subscribe for 6/12 months up front.
Been worth it's weight in gold in complete truth, one click of a button and you can switch to another ip, they run fast and when you start creating an auto approve list you'll be onto a winner.
I've had Scrapebox for about 3 weeks now, and my auto approve list is around 50k and growing, sites are already moving up - it's all going really well so far, i'm really impressed!
