I feel you man, it's so hard to predict sometimes, too, even if you put effort into finding serious-looking projects. Some people just really lack respect for other people's work. I get especially antsy when the original text's English isn't very good and you have to guess what the author was trying to say. If you translate what's in the text, you get nonsense. If you make an educated guess what it should say, you're technically not doing your job right. It's just impossible to win.
