I have no idea when people here got the impression that this was a gossip chat room, but it isn't. In case it wasn't clear from our "one user, one account" policy, we do not allow banned posters to re-register, and thus we do not allow current posters to act as proxy reposters for banned users. In addition, the site being cross-linked from is part of a banned site (which is why no one is posting links to it).
Looking through search results, it seems this has been pretty much constant since his/her previous account was banned. This is not welcome.
As a comment on NDP_Mulcair: This account was registered by someone purporting to be George Terhanian, President and Chief of Research for NPD under the username NPD_George. The first red flag was that the user was registering using a disposable email from an ISP rather than a work email. We quickly used the same forensics we use on other purported celebrity accounts and determined that the account was not who they said they were. We do not make public the information we use to do this kind of verification.
We verify accounts like this because GAF is a big site and many people have done celebrity impersonation attempts, including most recently a user banned for claiming to be Ronda Rousey, but also notably Zelda Williams (including roleplaying being upset about her Dad passing) and Aisha Tyler (the current Aisha Tyler account is the real deal). Once we determined that NPD_George was not who they said they were, we renamed the account to another name to mitigate the risk of celebrity impersonation. It is worth noting that the user in question did not express any confusion or contact any of us at the time.
The user in question continued to post. We applied further forensics and determined the account was being used by a previously banned user. As a result, we banned the user for circumventing a previous permanent ban. The user responsible for the account had been previously banned several times for creating accounts to circumvent previous bans. We often apply a little bit of flexibility and leeway when it comes to, for example, people banned a decade ago and reformed (in this thread alone, Square2015 is Square2005! Surprise!), but a serial re-registerer who keeps getting on our radar clearly has no intention to obey the rules, and thus they are removed. Again, our ability to detect alt accounts is fairly sophisticated and gets better all the time. It's not perfect, and it's not immediate, but it's also not stupid. We aren't idiots. And in point of fact, even without any of the forensics, it is typically not difficult -- many if not most of our alternate account detections come from ordinary users observing that someone is plainly an alternate account.
If due to some cosmically unlikely coincidence the actual George Terhanian was banned from NeoGAF, I invite them to contact firstname.lastname@example.org from their NPD email and ask to be unbanned when he certifies his identity. We would be happy to have the real George Terhanian as a poster here.
We invite posters to continue posting reliably sourced information that they find online. Recognizing that many people banned from GAF are original sources of information, it is probably impossible to prevent useful information being posted just because it is from a tainted source, but gossip about a previously banned member should not be the primary subject of the NPD threads, and if it is going to be, we will simply not have NPD threads.
