I am working on a "database" style of program that logs data such as an IP address, Steam Name, and Steam64 ID. I own a small game server company that hosts servers for a game called "Unturned" but we also plans on having servers for more games. I have a few deals with similar gaming communities, however, their staff tend to join my servers and crash them. Just to have more players join their servers.
The Use of this program is that I can put in an IP address and check if it has any Alts on record with the same IP address. So in case it is a staff member of one of these communities I can report that back to management of that community. This program does not automatically log Ip addresses, Only if I manually log them. I'm just wanting to know if there is anything illegal with this before I put it into action. (For those who do not know what a Steam name is or a Steam64 ID, A steam name is an online name, no connection to a real name, and can be changed freely. A steam64 ID is a number used to identify a steam account and is found in the user's profile URL) (I am in Australia)
