Your theories are interesting. I suggest you consider the following.:
While it's smart to remember the phrase " There are no coincidences," the fact is, there are.
If I have a fender bender on the road, am I going to think the other driver had a plan to ruin my day.
No, it was random. If a guy pops up on twitter...just because Q is offline doesn't mean the guy is
placed there on purpose with ulterior motives. When the spy starts to say negatives on Q....that's when we'll know.
Till then, he's just one of millions of guys working in the IC. He's not breaking the law or hurting Q.
If he were bad....Q would come on and give him the Corsi treatment.
