One of the problems I've run into with using a vpn service is that many services block IPs from common vpn services. While this may be due to abuse originating from those IPs this still seems like a lazy approach to abuse prevention.

One approach that could work around this in many cases is to run a VPS with a private VPN server on a cloud provider. This is beyond the technical ability of the average user though and costs more than most VPN services.
