Not sure if "i was actually testing" is a valid defense against cheating/duping/etc. Even if you are actually testing.
One of things to consider is what if someone else sees you? What if they post on their own private clan forum "i saw a tog guy duping/cheating/etc" - suddenly the number of people who hold tog in low regard is rapidly growing. Then it spreads by word of mouth. And that is all before you can say "nah wait seriously, i am actually a qualified software tester" - by the time it comes out on a public forum it's already too late.
That's probably why even legit testing is either flat out not allowed or very very borderline/greyarea.
