Fake Sal Khan?

There's this account that recently started commenting on various posts and poses to be Sal Khan. Now, I doubt this is the real Sal Khan because there is already a Sal account on Khan, with his Black Hold Badges and stuff. Also, the fake account's comments and answers are often unprofessional, with poor grammar, and typos, and not on topic. Hopefully, this account gets removed or forced to change its username to keep other users from being misled. The fake Sal Khan account is called: @SalKhanAcademyOfficial
