Seems to "on the nose" to be him. To us it seems like it's just some closeted redneck MAGA shut-in that has a homoerotic thing for Kyle.
Isn't that basically Kyle though? No friends, hick from the sticks, essentially a shut-in when he's not out filming in his bubble, MAGA, and obsessed with himself to a homoerotic degree (the Gaston flexing in the mirror, calling himself "stud").
If that's the case and it's a fan, then this person must also be Kyle's long lost twin since they type and spell exactly like Kyle, use the same filler words, and have the same problem with using adages correctly. Kyle often mentions how he has trouble sleeping and Peter is conveniently online until 3AM every night (except when Taylor visited and when he was at Disneyland). And they must be such a fan that they have Kyle's name in their email address. This must also mean that Farida is likely not his sister.
At this point there's just so many glaring indicators and evidence, that I'm not sure how it could be classified as "conspiracy theory." If it seems "too obvious" we have to remember this is Kyle Pallo, a very mentally stunted individual. I often think, who would have the motive to be this concerned over Tattle and critical comments toward Kyle? The only group that matches is his "team," who'd have this much of a vested interest in propping him up. And if it were his family, they'd also have the motive to use sock puppet accounts to conceal themselves.
