FWIW, Scott Westerfeld used a trailer for his new YA trilogy last year (it was excellent. this is not that). Just sayin it's not unheard of.
Also, re: bumble- I can't produce any actual profile information, but I matched with AA on Bumble about 6 months ago and exchanged a few messages, IIRC, before blocking/deleting. Like most have been saying, he seemed off, and was too eager to meet in person without actually caring to learn anything about me, or that was how I perceived it. He used the name AJ on the app. I realized tthis a few days/threads ago when his social media started cropping up and I recognized some of the photos. They seemed to be older photos, the one with the glasses and the cream colored sweater with the plaid lines, the one with the (I think we determined) headphones around his neck, and some fitness-model-y type ones. Definitely presenting himself to be more fit than at time of arrest, IMO. Just my perspective since a couple of you were asking about that profile/app. (Actually now that I think about it, could have been tinder or bumble. I can't be certain since I deleted it, but my memory says bumble.)
