I don't think its so much making fun of the OP as it is making fun of his request.
Its not funny to have a serious fear of something, but its laughable to demand said thing be removed from a game otherwise you won't buy it. I could think of a dozen things in an Elder Scrolls game that someone might have a serious fear of... and there is no way the developers can make a patch to remove every one of them, and they shouldn't try. The simple fact of the matter is if you can't play the game because it has a couple spiders in it, well then don't buy it.
It is possible the OP could ask a modder nicely to remove the spiders from the game for him. But don't sit here and threaten the developers that you won't buy the game if they don't do exactly what you want.... its not going to work.
