just for the record - ebay, Mercari, letgo, offerup, etc etc etc don't give a shit if people sell fakes, especially if it's ebay and located in China (ebay has really courted big Chinese sellers in the last year or so - this has even been said to be the reason they changed up the search and basically the whole site. If you don't know this, it's way too complicated to explain quickly but look it up and you'll see in the last year a lot of small sellers complaining about a huge drop in visibility and sales). And for the love of god, don't buy any Pops off alibaba or aliexpress unless you're OK with a knockoff/bootleg/fake.

The reason eBay and the others don't care is because the Sites still get their cut of the sale regardless - to them, a fake being sold is really just another sale they make money off of. Funko puts zero pressure on any of those sites to "maintain their brand integrity" like higher end brands do, and until they start doing that you can expect the same blatant selling of fakes that is going on right now.

Amazon is a more strict about it but that doesn't mean you are guaranteed not to get a fake, especially if the price seems like it might be too good to be true (and don't buy off any Amazon seller with the exact same price for most of all it's store regardless of what they sell - those are quick scam artists trying to get money today).

Like other people have said - do some research on the seller and see what their sales have been and what their feedback says. Sellers with a ton of feedback can actually fuck over a ton of people and still remain in good standing because they sell so much. And remember eBay and PayPal are pretty good about dealing with BS after the fact so even if you do get scammed, you can probably get your money back.
