I don't even think she can do that, there would need to be a clear screen recording from the live of someone clicking her account and showing all her info, followers, users, videos and I don't believe it exists. I think Alex is just hoping people take his word as gospel.
I would be curious to see it though, even just of the live. Because if Sqeaks sides whos thing is denying they ever spoke about Kelly's uncle, I don't understand why that comment would be made or left without them addressing it. And if they addressed it they'd surely click the account to check who it was? Because even if it's a fake account and they let the account say that, it goes against what they've been denying too....
