What do you think? No reason for questions being deleted?

I presume they are deleting our questions due to answers we receive.
Perhaps someone leaves a vulgar answer and someone reports it.
Would they delete our question because of a persons answer?
I had a question as simplistic as "know any good game sites?" and it was deleted. I only had one answer and never had a chance to read it before it was deleted.
Do you know, or what do you think?

It it's true that they delete just because it's reported would mean that Yahoo doesn't read them first... Thay just automatically delete it?

I have a theory that the person doing the deletions is just having a bad hair day and taking it out on us. Seems no other reason sometimes!
