Confirmation bias. If, hypothetically, 99% of bots were banned and there's enough lingering, you would doubt it to be true. Although, I tend to agree with you about spam prevalence. I've reported dozens of spam/scams/fake accounts and almost every time, I'm told that the post/account "doesn't violate [their] community standards."
