I think it's simply that OP follows him, he tweets a lot, and OP is a Lemmy power user so posts his tweets here frequently. Any time I see his tweets it's always been posted by OP; I've seen some users suspect OP of being a bot but given the amount of regular comments they also post I feel like it might just be someone who has a pretty regular routine of posting stuff they've found during the day.
All just speculation from me though...
Yeah normally in these older photos no one looks attractive but even with all the things you mentioned against her she's looking pretty good.
Turns out when he proposed his theory of everyone being attracted their mum he actually meant his mum.
