help code for sources mu emu autodisconnect

Hello
Someone will have a disconnection code for the source mu emu
The idea is to have a connected account disconnect when it is login again

Because some leave the account locked up and someone kills them then they appear in safe..and lose lvl .. a friend wants to connect that account to return to lvl and can not because it is connected .. then the idea would be that. Disconnect a connected account. Connecting it again.

That system of auto disconnect I saw it on some servers that is why I would like to know if someone has it .. I think it goes in the joinserver .. but I am not very sure

regards
