As a newer user on Ask Ubuntu I have seen activity from older (higher ranked) users that they themselves would count as off-topic. For example questions on EOL versions or versions that are soon to come. I have seen this more then a few times by different older user that then comment on another post saying that it is off-topic because it is EOL or not released or whatever the matter may be. So why is this so excepted by Admins or the "community" in Ask Ubuntu and not more frowned at? (We should all have the same ability to ask questions and follow the same rules regardless of how often you are on or how high your rank is lead by example??!!)
Some of the questions aren't necessarily off-topic, as the person asking question may mention their release version, but the problem doesn't relate to the version of Ubuntu specifically : for instance, a networking or scripting question would not be off topic. Questions where the issue is clearly related to the OS version being unsupported already, it's good call to close and advise the user to upgrade.
There's no privilege for higher ranked users as far as closing or not closing questions goes. But higher users may exercise better judgement when flagging a question.
