Edit: I want it iterate whether these are permanent or not is currently speculation, but so far everyone I've talked to who received the "Our servers are humbled by your incredible response"/"failed to get game data from server" has still been unable to log in. It has been 12-24 hours for a lot of people so far. This ban is not the same as a softban, they did add new softbans recently see below. Also it seems to only be botters who have had this happen, and most botters still have not been banned. Finally, no this is not a server issue. Yes you can get this message during server errors, but if you get it only on one account for an extended duration, it is a ban.
