I would not trust it. To run multiple copies I suggest D2Loader
If part of the URL is stared out, replace it with n-e-w-d-2-e-v-e-n-t (no -).
Download the latest version. On that page will be instructions on how to run multiple copies of Diablo 2 (You will need more then one set of CD keys, if you look on that site there is a link to a file with a list of nearly 1000 diablo 2 CD Keys, some are banned but you can try those, it is the first link underneath Diablo2 download).
Additional Comment:
I have heard of other ways of doing it without D2Loader, I will get back to you.
D2Loader will not get you banned. In case you wanted to know. Whether or not they will ban you if they find out you used it to run multiple Diablo 2s, that I do not know.
