Advertisers need to select subreddits that fit their niche better. Yes there is porn on reddit, but that shouldn't stop amazon from advertising on /r/books. Not all subreddits are equally suited for ads, but some of the subreddits are going to get people to stay. So if you come for /r/gonewild, you might end up going to /r/books and buy a nice e-reader. Now if advertisers don't, or can't, target their ads to nices, then those ads don't need to be on reddit in the first place, and the people making those campaigns should not work in marketing.
