For some simple work a VPN is good, or even better if you just need to access some blocked site, social media and stuff like that. In general, I would recommend a VPN to anyone who also wants to be safer online. But for work, like in my case for multi-accounting, then proxies. I currently use proxies from https://www.simplynode.io/. They don't have dedicated proxies, but they do have sticky sessions to lock an ip to an account for a few hours. That works for me.
