Another creator trying to buy a large portion of my content library. Would you consider this particularly suspicious?

TLDR
I've sat across this exact DM more times than I can count, and it never stops being uncomfortable. Someone offering thousands of dollars for your library isn't automatically a scammer - but the fact that nothing looks fake is exactly why you should slow down before hitting send.
If her account looks legit, why does it still feel off?
Because "looks legit" is the cheapest thing to fake in this business. A verified Fansly account with posting history and connected socials doesn't cost much to build or rent, and hijacked accounts get traded around constantly. Here's the thing the poster's own husband story proves: he sold clips to a creator who had a "valid history of posting and selling her own content" - and that turned out to be the very thing worth noticing. Creator status cuts both ways. A fan who loves your work behaves like a fan: small purchases, tips, comments, engagement over months. What she's describing - "I'll take X amount of BJ videos, what's your bundle rate?" - is procurement language. It reads like inventory shopping, not fandom.
Also worth naming: the poster ranked four scenarios and missed the most boring, most likely ones. Reselling at a markup under different branding. Splitting her library into smaller clips and repackaging it across accounts. Or running a "warehouse" profile collecting content for an aggregator or scrape. Face swapping gets all the attention because it's scary, but it's also the hardest option on the list - reselling your work under new watermarks takes an afternoon and zero skill.
So how do you actually weigh the risk here?
Stop asking "is she legit?" - you can't know that, and nobody honest on either side can. Ask the better question: what's my downside in each direction? If she's a genuine superfan, declining costs you one sale you'd have made anyway. If she isn't, you've handed over your entire library permanently - she has the files, you have a chargeback notice and a takedown fight ahead of you. That asymmetry alone justifies caution, and it's why "am I being paranoid?" is the wrong worry. Losing a legit buyer is recoverable. Losing your catalog isn't.
If you do decide to sell (and selling isn't crazy - people do bulk-buy legitimately), shrink the blast radius: cap the order size, deliver in stages across weeks, watermark everything, keep records of the transaction, and set up alerts on your own content so you catch reposts fast. And keep it all on-platform. Off-platform payments feel like a workaround but they strip away your only recourse and add new fraud vectors.
Where does the line sit between smart business and paranoia?
Honestly, I think refusing a full-library sale to another creator is a perfectly reasonable low-cost default - protect the bulk, sell the singles. If someone genuinely wants your work that badly, staged batches and caps won't scare off a real fan, but they will exhaust a reseller who wanted one clean transaction. That's a feature, not a bug.
And if streaming is your lane - live interaction, real fans tipping in the moment instead of someone DMing you about bundle rates - that whole risk profile shrinks. It's one of the reasons I keep recommending xlovecam to creators: you're selling your time and attention live, not handing over files that can be resold while you sleep. So the question worth sitting with is this: what does your actual business look like in six months if your library walks out the door today?
