Niggas pay to e date
Isn't there an entire fetish that's just about being indebted to someone?
This can't be the first time you've heard of sugar daddies being scammed, it's so common that they even feature this shit on Reality TV with shit like 90 Day Fiance. It's no mystery why it's becoming increasingly common to catfish; There's some sad motherfuckers out there like Med who will pay for you to string them along (literally if you give them the time of day too much they'll get bored of you, they just want the chase).
The App Market refers to people like Med as "Cash Whales".
Otherwise to answer Quora's question, the racket that allows for online only theft like that comes from the desperate LDR market, and usually only if you're from a poorer easier to take advantage of country. Thailand's trying to own this market pretty hard right now.
In defense of e-Dating, trends are changing. Where before people were more prone to online-only relationships from "having been on the internet in the first place", this model has trended past them and onto people who actually go outside. What before was about having fewer options has changed into a much pickier system, one pickier than just being a pick up artist in real life.
People IRL find it flattering enough to be listened to and appreciated, while people online are much more prone to tribalism through archetypes and tropes.
People are much more willing to bridge the gap than they've ever been. Back when I was visiting people I was meeting on forums it was unusual, but nowadays it's more about how many of them you've met.
