Are VPN important if I'm just exploring Twitter?

I want massively scan Twitter and record all the activity of certain subnet where some specific accounts have activity.

I know that VPNs are important working with bots (twitting, following, etc), but I just want to get info using the Twitter API. For this purpose, it's important use VPNs? Sending queries from different Twitter accounts from the same IP will cause any ban?

Thanks!
