Thank you for your well considered vote of confidence in our "weak moderation" Just This Once....
I wonder if you realise that the 2 people moderating this forum (which used to be completely unmoderated incidentally - I guess that was weaker moderation huh?) also have responsibility for other forums, and thus might find it a bit tricky to follow absolutely each and every post in the forums for which they have a responsibility.
Rather than whining about weak moderation, why not use the "report post" function and get our attention on such things. Oh yes --- somebody did just that, and you will find that the miscreant is "in limbo" for a while.
Stop whining and take action!
