Decided to check in on Scruff and it's just an endless parade of 6'4, 236-pound nonsense slop machines.
All of these lines are setting up a "cocky alpha" persona where the object of desire doesn't care about you, and I think that's intentional. That persona is intensely attractive to some people, and it means the bots don't have to deliver much, can get away with incoherent responses, and never have to meet in person. I imagine the goal is to funnel submissive men into findom arrangements where they tribute money to the bot in exchange for photos & chat. Maybe pig-butchering leadgen.
More broadly... We're still in the infancy of bots on social media and dating sites. These ones are obvious, but there are more sophisticated ones out there, and they will become less detectable with time. I dunno whether The Apps will disappear entirely, but I do suspect in ~5 years it'll be routine to ignore anyone who won't meet in person, or who I can't verify through mutual acquaintances.
Probably 90% of woof.group's signup requests are bots now, BTW.
