[Pen] I was about to agree wholeheartedly (and indeed KS's first line was singularly juvenile), but I went to the game and in fact there aren't any crude limericks currently on the top page. So, although I agree with your sentiment, you may actually be overstating the issue. Actually, I think we went through a dip into the area where saucy starts bordering on filthy a couple of weeks ago and have climbed out again.

Maybe you're influenced by the output on MCiOS - but I wouldn't class any of the currently visible lot as more than saucy.

Also, I don't actually think tits do like melons.

I'm with penelope in this instance. That line was pathetic, and completely out of keeping with the tone of the website.
More generally [SM] I believe your example #1 shows the type of limerick many of us prefer. The form may have its root in ribaldry, but there's a clear market for amusing rhymes and syllabic dexterity rather than innuendo.

*waves from Strasbourg* Well, I've emerged victorious from my part 1 exams - what are we all up to this weekend?
