What about data center IPs? A pay-by-the-hour VPS can be cheaper than any VPN service. I've been using one recently and it hasn't been flagged by any site I care about.
Not me. I'm very happen when this happens. When it comes to identity, it's far easier to deal with false positive than theft. For example, my credit card gets flagged for fraud every holiday when I go on a gift card purchasing spree. I have no problem with this.
