I think I’d like to know the amounts we are talking about before declaring fraud. While we know the number of transactions the actual $$$ has been left out. Meaning we are drawing our own conclusions. Nature abhors a vacuum and all that.
I wouldn't assert that it is fraud, that's a pretty bold accusation . But I am convinced the OP was sailing close to the wind. QF's actions are the only thing upon which we can draw a conclusion, and they wouldn't take such a step unless something flagged some sort of behaviour that (at best) isn't in the spirit of the program.
