source for good proxies - or maybe I'm doing something wrong with YPP?

A friend of mine picked up 10 private proxies from YPP for use with scrapebox about a week ago. He noticed today, that every single IP was banned by akismet. I first considered that maybe he had gotten them banned via his own actions over the past week, but he swapped them with new IP's also from YPP and those were also all banned in akismet already.

I bought my own 10 IP package, hadn't used them for any posts at all yet, and attempted to post to that friend's wordpress blog in order to test them. All of my own fresh proxies which I never used, are also already banned by akismet.

I'm not sure if I've done something wrong - although considering that akismet flagged the IP's as spam upon my 1st post, I doubt it - or if maybe the proxies I received are just duds, perhaps due to overuse and being recycled from a previous customer who got them banned.

Any ideas what I should try? Is there a better source of proxies than YPP? Or is this more likely noobie user error on my part?

Thanks.

btw, before anyone asks, random names, emails, and domains were used. the only constant was the IP's.

You can just pm me your email, and ill replace your proxies in an hour.

thanks jaerehan, I sent you a PM.
