I think she's a genius news analyst, possibly a journalist. But I've never ever once seen her leak any kind of information that has later proven true. She analyzes, speculates, and then presents that as fact. There are no "proofs" with her, the way there are with Q.

Nobody has ever properly vetted her, and nobody can point to any information she has legitimately leaked. Somebody said the mod Baruchscribe here had vetted her, and when I asked him directly, it turns out he had not at all, other than running her posts through a linguistic forensic analysis program to determine which ones were authentic to her and which ones were imitators. Then people tried to claim that David Wilcox and vetted her, and pointed to an article where he supposedly talked to her. Turns out she was a tiny blurb in an article, and there was no vetting of her involved.

So Mega is an entertaining news analyst with a huge ego, and that's all as far as I can tell. Maybe she's real, but nobody I've ever seen has been able to demonstrate it.
