I think Mr. MOD should warn or block people who
making fun of people for their serious question.

I too have noticed many comments are gender biased.
If a lady ask some question people just say something irrelevant. It is just like they want to show their presence here.

Mods are already doing an excellent job maintaining
QL very well as it is really difficult to keep an
eye all threads and all comments.

so the best option is to use the report/flag/abusive buttons.
