I should admit that I donated to them once after a preliminary cross-check. However, it seems I still got fooled. After that they started calling me at any time for more donations, and tried to use their “pressure” tactics. I requested them many times not to call me, but just send me an email. However, they continue to ignore this and call me up at odd hours (sometimes). Anyway some more Googling brought me to this post. This post looks genuine enough, if you read its long comments section.
