I think it's believable, for Seymour. He is a man who still thinks of digital in the same vein as physical - you need right connections, put some effort, and everything can be done. But yeah, it's a worthless threat.
Hack Stalkfap? Not really possible - Seymour isn't deep in tech for that, and I believe security for such media is more than high.
Connect with SF owners to take it down? Possible, but unlikely. They might take a bribe, but this won't be good for their business to be caught, and they don't really have any interest unless it's a *massive* bribe - Seymour is of zero interest for them.
Buy it? Not only it's a waste of money, but ownership of adult social media is a heavy hit on his public reputation.
Just leak the photos? Oh no, a well-known nude model who poses for exhibitions and advertises her OnlyFans has her onlyfans leaked. That's literally not the news, and has around zero impact on her prospects outside of some modelling agencies, and even then, they would most likely just act to delete it.
Put her to court for breaching the contract? Possible, but it's more of a hit for Seymour's reputation, and maximum damage is a couple of months' rent.
For SFW social media to delete someone's account, you need either their personal interest (like Trump), interest from the government (and Seymour is playing in the kiddies pool of city elections), or, the best case, having a policy of autotakedowns for copyright infringement, which can be reversed.
But SF is NSFW media. Pornhub dukes it out with European Union and USA state governments, they won't cave to some moderately filthy rich guy. You need CP concerns for a takedown, or, again, a massive bribe, and even that is unlikely.
Cancel? Again, she is a public nude model who advertises her SF in her Insta - nothing sexual outside of illegal is a threat to her reputation. Lena also doesn't have a job worth the effort - she works in a cafe, and owners are treating her practically like her daughter. Destroying the cafe is possible and Seymour is petty enough to do that. But so what? She can apply to any other waitress job. She can skip town in the worst case, and do modelling there - he isn't able to stalk every modelling agency, and out of town, his influence is much less.
In the town, Seymour is a big fish, but the world is an ocean, and he is insignificant in comparison. What he can do? He can try to punish Ian and Van Dykes. He can go all in for an election to use administrative resource later (again, skipping town). The worst would probably leaking evidence of her cheating, but that ship has sailed in C12.
So, in the end, you can't stop the signal.
(Also, I still root for Stan's fedora/Perry route)
