It should be old news by now that if you see a questionable video on Facebook you probably should not click on it, and definitely don’t give any information or fill out a survey. But with the shear number of fake videos popping up and scammers relentless tactics, it can be difficult to discern which videos are fake and which your friends post because they actually want to share an interesting video.

The most recent of these fake videos is one claiming to depict a roller coaster accident in California. Variations talk about it being in the United Kingdom, Australia or Universal Studios. Basically if it claims a roller coaster accident in the title it is a scam. No such video exists.

False Video Links like this have been cropping up on Facebook for some time now. Some other ones to watch out for are claims of a sex tape involving Justin Bieber or a supposedly embarrassing video of Rihanna.

Scammers tend to post “videos” that people will click on out of morbid curiosity. They want you to click without thinking.

The scammers earn money by driving traffic to certain sites. They get paid for each survey you unwittingly complete, or any product you purchase, or even just by compromising your Facebook account. Many are designed to spread malware or are linked to phishing scams, whose sole purpose is to obtain your personal information.

The best way to avoid these kind of scams it to not click on friends video shares at all, or just use some common sense to determine which videos are most likely fake. Look for videos that are designed to exploit that part of you that can’t help but watch a train wreck. If it looks gross, morbid, or involves sex, don’t click. If it links to a page that doesn’t appear to be a reputable news source, don’t click. Also watch out for the language usage in the description. Many make grammatical errors, or generally don’t sound like the way people talk.
