1 Did aTriz see the script?
2 Did he test the said script?
3 If he did, did he profit from the script.
4 Can he say with certainty, that the profit accrued was due to the fantastic machinations of the script.
5 Is he still using the script? and what are the results? I see no reason why he should stop using it, according to him, the results are fantastic.

If he answers no to these questions, could he have been coerced somehow to make the vouch?

I rest until whenever aTriz answers these questions. Bear in mind that only aTriz aside from the proven liar alia has seen and used this script. Only atriz can tell us if or not the said script is real or a scam.
