Sure, what a string of coincidences
Btw, this place is pretty huge, both in number of users and subforums, there are people with 10k+ posts who are almost unknown outside of subforum(s) where they frequent. If anyone succeeds to get flagged here as a double account after a mere 50-100 posts or so, that alone says enough
Well, anything's possible with anonymity
If you want to dig further down the rabbit hole, the Mods will have to meet JG (and his 'friend' if applicable) in person to get genuine evidence.
