Marlon's account is not a fake. Jermaine himself tweeted from it to announce his new personal page.
Jermaine is clearly tweeting this to see who will jump the TS ship because of it. I mean, TS is on leave of absence. The J5 page was involved in BIG proof in TS's legitimate insider status. Now Jermaine gets loud and public that it's a fake when it's certainly and quite obviously not. People are getting frustrated and the tone is shifting. The trial is approaching and TMZ is really pouring it on.
I sense some testing and weeding out going on...
It's not a fake unless of course THEY'RE the ones doing the faking.
