I looked at the first four pages of it and was looking for a flat-out denial from PrimeNumber7 that he isn't an alt of Quickseller and didn't see anything of the sort. Quickseller even posted in it and also didn't deny it. That says a lot, and that's in addition to the evidence you presented in the OP of that thread. So fuck me, I got snookered.
Is that how you judge if something someone says about someone is true? They didn't deny it, therefore it must be true. That is an interesting way of judging people. Normally, it is up to the accuser to prove their point, not the accused to prove their innocence.
Anyway, I am happy to see PN7 reach the rank of legendary. I would drop some merit on the OP, but I don't want to have drama involving allegedly giving merit to myself, so I will find other people with good posts to give my merit away to.
