When it comes to consumer internet services, the US is a 3rd world country, which is kinda odd considering most of the western world does their business there.
I just checked the terms on my 300/300 fiber connection, as well as my (backup, company paid) 25/5 ADSL.
They're almost identical:
* no spamming. * no racism/unethical behavior. * no portscanning. * no illegal downloads/uploads.
Besides that i can use it for whatever i like. They block port 25 though, and you can only get it opened by purchasing a commercial connection. It has a dynamic IP address that only changes when i reboot my modem, which happens once every 2 years or so, so practically static IP :)
The ADSL has all ports open and a staic IP.
