True 
but this illustrates the reason behind my point in those other topics, e.g. (Glicko-2 does not require accounts to start at 12 kyu. So why do we do that? - #62 by dragon-devourer)
Although in this case (with default initial rating, rather than declared initial rating as proposed and discussed in that other topic) it’s to allow players of any level to avoid games with [?] accounts that may be backed by an incorrect rating due to the default initial value being way off for that player.
The point is, some players don’t mind playing [?] opponents. Maybe they do it to support new accounts in getting a stable rank. Maybe they just don’t know or don’t care.
But some players do mind, such as the OP of this topic. And there may well be valid reasons for this. Maybe they’re sick of getting trolled by sandbaggers / airbaggers if their level is particularly susceptible to that. Maybe they are generally anxious in the face of uncertainty so would prefer to know their opponents’ ranks. Maybe they are working hard on their own Go playing development and don’t want to waste their time on games that will not give a decent rank boost if they win (which is true of games against [?] accounts as the high deviation means the rating change is relatively small compared to a game against an opponent with an established rank).
Whatever the reason, players should be able to avoid games with [?] accounts if they wish. I suspect that, in reality, it is likely that only a relatively small proportion of players would use this option if it existed. In the unlikely scenario that so may players use this option that it becomes difficult for [?] accounts to get games so they become stuck in the [?] stage:
-
This would be further evidence that there is a problem with the current [?] system, so it needs to be changed anyway
-
The [?] accounts can just play a few bot games to get a non-provisional rank and then they can play games at the correct level
As for the OP, as a workaround, you could try to restrict rank such that 5-7 kyu are excluded as new accounts are initialized at ~6 kyu. This won’t avoid games against [?] accounts completely, but it will reduce the probability of getting games against them. Not so useful if you’re looking for opponents in this range thought
