A recent suggested tag-wiki edit for example:
Glitch is a web-based massively-multiplayer game which takes place inside the minds of eleven peculiarly imaginative Giants. If your question is about glitches in a game, please use the bug tag instead.
glitch-strategy.com URL (Strategy and Wiki links above) isn't officially sponsored/sanctioned, so I'm not sure if those sorts of links should be included. It could lead to a slippery slope of including every resource for game X as people could argue "well, if you have leaguecraft.com on there then you obviously should have mobafire.com..." etc.
The reject button didn't bring up any particularly good reasons to refuse the edit (are all the reasons canned, you can't type one?), "Vandalism" for promotional things seemed a bit extreme.
