Yep, I worked on a website for a very popular British girl band almost ten years ago. The target demographic was teenage girls, and one of the requested features was to embed a Twitter feed showing a particular hashtag on the homepage to promote their album launch. The client thought it would be quick and simple because Twitter supplies that kind of thing as one line of code, however since it was pulling directly from Twitter in the browser, there was no opportunity to moderate if we did it that way. We pointed this out, with the consequences, several times, and strongly recommended that we pull it server-side so we could provide moderation, but this took extra time and money, so the client ignored us. Fast forward to the site / album launch, and sure enough, right in the middle of the big publicity campaign, some bright spark decided to tweet altered obscene song lyrics describing in graphic detail what he wanted to do to the girl band members, using the hashtag so it would show up on the website viewed by all those teenage girls. This kind of thing is entirely predictable, but the people in charge of these things are often inexperienced, overworked, and inattentive. Couple that with somebody telling them that it's going to cost more and take longer to do it properly, and they are going to go with the quicker, cheaper option unless they've been burnt by this before.
