I noticed a person named Alexandra Migoya as the one who posted that Instagram photo with the caption "double sleepover to kick off at Comet Pizza", so out of curiosity I searched her name on Google and found that she had deleted her Twitter and set her Instagram to private. However what did come up is that she is on one of the committees of something called the Transformer Annual Silent Auction and Benefit Party (she's on at least the 9th and 13th editions), which has among their corporate sponsors Occasions Catering and Comet Pizza, and has James Alefantis on their board of directors. If you notice on the link I provided, Occasions use the squiggly spiral logo, not the triangle one used in Besta's old logo, but the circular one depicted from the FBI document (I linked to it so you can compare) meaning "little boy lover" vs just "boy lover". Furthermore they have a section specifically dedicated to kids, on only on the kids menu in the background you can see a bow which is similar to the cross symbol depicted in the FBI document and found on Comet Pizza's menu. As for the Transformer event, some of the artwork for auction is pretty weird. One called PPPP, People's Ping Pong Party, another called "visions of the end of the world" depicting an eye in the clouds with a mutilated bloody body on the ground below, if you go to other years you can see more creepy ones.

Lastly, not sure if this is relevant but when searching her name on Google this photo keeps coming up from someone called Alexandra Javier on Pinterest, not sure if it's the same person or if not who this person is, but it is pretty creepy and keeps coming up in my searches for Alexandra Migoya. If you check out the Pinterest she has a whole section on unsettling children and toddlers wearing cutsie outfits like this.
