What's the purpose of the "Hmm... you seem to have a lot of punctuation" balloon in Yahoo Answers?

It seems that almost every time I write something in Yahoo Answers, I get a balloon that pops up advising me that I seem to have a lot of punctuation in what I've written (for those of you who haven't seen it, it's just like the one that tells you when you've misspelled a word but it says, "Hmm... you seem to have a lot of punctuation").

Each time I've re-read what I wrote and I'm quite happy with the level of punctuation... seems to me to be consistent with standard written English.

So what's the purpose of the balloon? Could it be that I'm over punctuating? Or is it that the person who wrote the criteria for the balloon was raised on a continuous diet of SMS/IM and now honestly believes that that the only purpose for punctuation marks is to "bleep out" swear words in written communication?
