Because the 警備員 do not use anything to register to Donguri, the Donguri Base makes a hash of your ip address to create a reference to who you are. If your IP address changes, it cannot recognize who you are and will make a new 警備員 account for you automatically. This is important to prevent bots and arashi.
Uplift users have their ハンター accounts tied to the uplift login, so donguri always knows who they are. If you constantly lose your 警備員 account because your IP changes, then I recommend you purchase Uplift.
