The 'second' incident, as far as I know, was never repoted to myself or any other mod.
There is no real use comparing this forum to any other forum. A GFX forum, devoted to graphics, would no doubt have different rules, than one devoted to a text based game.
If you really feel the rules of sig use need changing, try again. Complaining at the lack of change, won't change anything in the long run, not if you aren't at least helping it yourself
