Proxies for Tweet Attacks?

Hi,
I understand that it is better to use proxies for follow/unfollow, and assign a certain proxy IP for each account, but Reply Module sends its replies from the web (as described), so, for using just a Reply Module proxies are not needed, right?
Thank you

I have the same question I hope someone answers it. Also what about disconnecting and reconnecting modem to get new IP isn't that a free way to get IP for this use?

Hmm this post has been sitting here for a couple of days...any takers?
