This is the official site of a Polish music copyright organisation (like MPA in the States, whose website, by the way, also has low WOT rating). You may not like them, you may think their business model is out of date, the copyright charges are a rip-off and the stickers they put on the CD covers are ugly. But this has nothing to do with their website, which is OK, and the organisation is legal.
Można nie lubić ZAIKSu, uważać, że prawa autorskie to przestarzały model biznesowy, a nalepki na okładkach płyt są brzydkie. Ale na WOT oceniamy bezpieczeństwo stron internetowych i ich legalność, a tutaj nie można niczego ZAIKSowi zarzucić.
Three of the four negative judgements about this site were written by one and the same person, who must have written them in a fit of anger. As four the fourth negative opinion I do not think stickers on CD boxes have anything to do with the trustworthiness of this site. After all, like it or not, ZAiKS is a serious institution.
