If you build and deploy an application on a server (so no client download), the main issue is all requests come from the server. i.e. all requests originate from the one IP = not a fun time.
Ah i see your point, therefore it could link any accounts who use the server together.
So if the IP is flagged it could cause problems for anyone who uses it.
Or gaia could ban/block said IP.
There's nothing ideal about being real, there's so many flaws to cover and conceal.
