Reputation gained from Grey quests

[Arael]

Grey quests awards only 1/5 of the reputation they should.

Bug?

Bump.

They are grey...I think you just answered your own question.

Full reputation is still gained by questing at a higher level. For example, completing low level quests with a level 80 character now gives full reputation. This makes it easier to get to exalted and buy another faction's mount.

who knows when that was changed...it does say lvl 80 in your quote

This applies for mobs too, so if you are thinking about grinding on those Desolace Centaurs, while you may kill them fast you will only get 1/5 of the reputation.

Reputation rewarded for killing mobs will no longer automatically deprecate. This means trivial mobs will continue to give out their full amounts of reputation on kill for the majority of cases in the game (level 70 creatures in Stratholme, for example, will continue to award the full amount of rep to level 80 players seeking to boost their Argent Dawn faction).

Reputation gains from quests and mobs were changed once in TBC and apparently once more during WotLK. Nostalrius currently has working vanilla scripting, meaning that you only get full reputation if the quest or mob is at least green.
