I formerly subscribed to Zagat Survey, an excellent review of restaurants, hotels, nightspots, etc., around the world. I also submitted many reviews, which were published online & in Zagat printed guides.
But now I don't subscribe; rather, I believe Zagat sucks.
What soured me? They've a scummy system that automatically renews subscriptions. They don't allow immediate opt-out. The system is skewed to their convenience: the user is automatically billed again next year, and again forever. They claim a call or letter later can end a subscription. But I don't wish to "subscribe for life until further notice" -- I'd be OK for a year, but this is bad practice. Zagat sucks.
