You can't blame bittrex. If they don't add the coins - mintpal/polo or some other exchange would anyway.
If you are unsure of a coin - get its source code and check it.
In this instance - it seems no one did:
>> pindexBest->nHeight+1!=1
Was in the codebase plain to see.
Not owning up to the problem is PART of the problem.
And not everyone can read code, so its not plain to see as you put it.
