People post questions on Meta that should really be on SO. (Latest example that'll doubtless be deleted momentarily.) They've been doing this for ages and the problem's been brought up on Meta at least a couple times.
In at least one case, now long deleted, a mod indicated that the poster was asking on Meta because they were blocked from asking questions on SO. Yannis alluded to that happening in a recent discussion, but didn't include any numbers. How common is this?
Those off-topic questions are generally very quickly downvoted, flagged, closed and deleted to oblivion, so they're not a (big) problem, but I'm curious as to whether it's usually an issue of genuine confusion or also frequently an ineffective attempt at avoiding a ban.
Does anyone with access to that info care to share hard data or even just their own impression?
