I logged on from the PC room, but it suddenly got deactivated

It was fine when I used it this morning and my account was suddenly disabled when I used it in a PC room in the afternoon. I just used it as usual, but it suddenly became inactive.I wonder if it's a indiscriminate Mugo van.. I used it as usual, and I didn't do anything to get into it It's so unfair. I hope you release it quickly..
