From "About" on the Facebook entry for tzarmedia.com on Feb. 5,2016:

Tzarmedia is your entertainment hub, offering movies, books, games, and music for one low monthly price. Oh, and we offer a 100% satisfaction guarantee!

(Don't you love that "Oh"?—It suggests a sudden afterthought, as if satisfaction were an unimportant little element in the transaction that TzarMedia had just decided to offer to each customer, as a "free gift!")

On that same Facebook page, mixed with the promotional posts from TzarMedia, were a series of customer complaints, each accompanied by a friendly, apologetic reply from TzarMedia, suggesting that the person contact *******@tzarmedia.com to request a refund.

I came across TzarMedia while researching movie scams of the "skimmer" type: the film buff attempts to play a movie on YouTube and is told to link to a different site to see the "full movie." If he does jump to the new site, he is asked to register a new account, with requires a credit card.

A "skimmer" website provides some desirable content, while also bilking the customer of small amounts of money, like a monthly fee for a supposedly free account, or an unwanted upgrade of the account to a "premium" (and more expensive) version. Sometimes there are charges for items the user did not actually buy. These websites don't make very much money from such nickel-and-dime scams, but there are so many of these mini-scams that they add up to a very good income for the scammers. If the customer complains, these websites often issue a refund, since they don't care about any one scam, just the cumulative total.

I didn't find a review of TzarMedia on SiteJabber, so I took a side trip to see if it had any negative reviews elsewhere. Here are some other places you can go to look for website ratings, and how TzarMedia was rated at each one (data obtained Feb. 5,2016):

ScamAnalyze (scamanalyze.com) - "Very Poor Reputation/May not be Safe to Use" Trust Rating 9%
AVGThreatLabs (avgthreatlabs.com) - "Currently safe (no active malware)" but only 25% positive (out of 28 votes).
WOT (Web of Trust) (mywot.com) - Trustworthiness = 9 (max. Is 100)

Some of these websites offer space for the user to post a comment. On WOT, for example, the 41 comments about TzarMedia are mostly of the type "they took my money for something that wasn't actually available from their website," and "they charged me for something I didn't buy." Each complaint was followed by a posting purportedly from a TzarMedia rep, apologizing for the mistake and offering a refund.

Bottom line: TzarMedia is not to be trusted.
