Proxygoblin + TweetAttacks Twitter Account Creator good combination?

Hi guys,

I'm going to be doing some blatant twitterspam. Already own tweetattacks, can anyone vouch for the 2 pieces of software I mentioned, especially in combination with eachother.

If I leave proxygoblin runnin 24/7 on a VPN, how many twitter-ready proxies am I looking at per day?

I don't see plugin support for TA. Anyway most of those software's just doing leeching from various forums with proxy lists and almost all lists of proxies are the same - slow, overused, raped and abused, so any software will do the work if you are ready to load it manually.
