Ok, I have a proxy network and I am getting close to 500 UV per day from yahoo answers alone..what shall i do to scale it up to say 2k-3k UV per day..

I don't want to submit to topsites cos most of them send traffic from Iran and Saudi. plus they lead to instant ban at schools..I don't want to do SEO either as I am busy SEOing up my other sites..
I am planning to submit to google/yahoo groups...

What more you think i should do??
