Guys it is unfair to blame Bittrex or any other exchange that adds a coin. The answer is sometimes right in front of you by applying good common sense and looking at the risk indicators. By looking at a few things you can make a call on the residual risk of a coin based on risk factors and then see how that fits into your risk appetite. You can then either stay away or risk it all and the alt-coin exchanges currently just provide a vehicle to cater for the whole of the spectrum of risk appetite.
In the absence of regulation in alt coins (self or otherwise) you can do certain basic things to protect yourself: Elite was high risk based on such an assessment, refer here

If you are unsure of a coin - get its source code and check it.
In this instance - it seems no one did:

Was in the codebase plain to see.
The lightning listing is an issue here. Coins are listed within a day of release, sometimes sooner.
The more competent members of the community simply do not have the time (nevermind the incentive) to check the codes.
Bittrex, who many traders assume would at least take a cursory look at the codes, does not consider this part of its responsibility.
