Feeling you are the only creative (web designer/web developer/graphic designer/logo designer) going through a period with a client from Hell? You are not alone. There is a site where creatives can post anonymously their clients-from-hell stories: Clients From Hell. It's a site mixed with the funny, sad to the gory tales of how clients can treat creatives.
However, there are some stories that come off as condescending and I do agree with some web designers who feel the site may be going bad. But we cannot invalidate the genuine stories of clients-from-hell posted on the site (and they make up most of the stories). Check this:
The common thread in all these stories is Injustice; the client commits an offence that damages the creatives situation somehow or is unfair to the creative in some way. This is a serious thing that cannot be dismissed.
Otherwise, if you are a creative dig into the site and see what trials others going through.
