My old ISP explicitly prohibited using well-known ports which was annoying because switching ports at the CDN layer isn't free or cheap. My new ISP does prohibit operating as a server for more than personal use at home, or something to that effect. I predominantly use my Sandstorm server for personal access and content, and since Cloudflare is CDNing the crud out of any public content I host, it should be negligible or unnoticeable, unless I host content that gets me in legal trouble enough for Cloudflare to out the real source.
