Ofcourse not, TSC. Look, even the smartest ain't putting up with everything. The fact that you're known for your perspectional savvy doesn't necessarily mean you wouldn't be tricked by trivial things... Do you know how inspired we(I) get to read properly constructed, point-driven post like yours, and many others? Lol.
Best way to know if account ownership didn't change (again) is to ask this member to sign a message from bitcoin address and prove ownership.

I've disposed of any hope I had that it'd change without Theymos resorting to the banning of all signature campaigns.
