According to this Facebook post, you can get 4 free tickets to the Six Flags amusement park just by sharing and commenting.
The post claims that every single person who shares and comments within 12 hours will receive the free tickets.
However, the post is fraudulent. It has no connection to Six Flags and no amount of sharing or commenting will get you any free tickets.
The post is just a scam designed to promote and gather likes for the bogus Facebook Page that published it. Via this ruse, the Facebook Page can gain many new likes. It can then launch survey scams or other types of fraudulent activity, this time to a much larger pool of potential victims
In some cases, the scam Facebook Page may be sold on the black market to other scammers.
Often, soon after one of the scam Pages is taken down, another almost identical scam Page will be put up to replace it.
If one of these scam posts crosses your Facebook News Feed, do not share, like, or comment on it. Doing so only helps the scammers. And, of course, you have no chance whatsoever of getting any of the promised free tickets, which never existed to begin with.
