Not sure what your offering for each email on this. If its a trial most have something in place to prevent the same IP from having multiple trials on it. Though perhaps youve found a trial that dosent. Though youde have to change names after every GB you grab which could be annoying.
If its through your ISP most have authentication setup. If your not a subscriber with them you wont be able to access the service generally. As for accessing multiple servers many have them. Theres no issue with subscribers accessing them all and could be combined for better speeds...
