I just think 'gambling problem' is too confusing an allegation to substantiate or dispel.
For people to read "BA has a gambling problem" and it put them off pursuing the man for refunds, because they believed he's gambled all their money away, would be wrong.

Growing up, my father was addicted to gambling. Fortunately he was rather good at it and it kept us in several homes & in private education.
However, the fact was, he had a gambling problem, even though he didn't have a financial problem.
So the phrase 'gambling problem' doesn't really help to clear anything up for anybody regarding their refunds.

As no one knows for sure exactly what BA's situation is, I think its best to avoid misleading rumours and stick to the facts.
