Speaking as a software engineer, no, it's not easy, and no it wouldn't solve anything because spammers and fraudsters are just as real as you and me are. Additionally to that, when signing up, one already is verified through their tax details and then later Stripe verifies them too after a certain threshold of income. Spam is not a Medium problem, it's an internet problem and a big one that's very difficult and costly to prevent. I can totally empathise with the platform's engineers having to deal with this. Not a fun one to solve.
