Believe it or not (I have a feeling you won't) but there were other people who suspected that PN7 is QS without my help. If I'm not mistaken nutildah himself figured it out on his own.
I too suspected that PrimeNumber7 was an alt of an active member almost immediately after noticing him. In fact I sent suchmoon a PM on June 20, 2019 expressing my suspicion that it was Quckseller. At the time I had noticed a few newbie accounts that raised my suspicions, including some that were registered in prior years who had only recently woken up.
That's why you're on TECSHARE's shitlist too - you think too much.
