We just had a crazy influx of new users in our title and we have no idea how nor what to do about it. The new accounts are all from android devices in China (where our app is not even available).
Could this possibly be some sort of attack?
The new users just absolutely spiked out of nowhere, as you can see in the graph. It happened for a few hours and then it completed came to a halt and it all went away. Hours later the same thing happen, generating 600 new users every 5 minutes and is still going on as i write this ticket. (see graph below)
Have you guys had any sort of experience with other titles that encountered this issue? What is the appropriate measure here? Should we try to block new users from China? Is that even possible in the PlayFab console?
Thank, any help would be greatly appreciated!
