I've found using a subdomain helps with that, spammers will try [e-mail] but won't bother trying to brute force subdomains.

However be warned some surprisingly large websites don't support subdomains, for example eBay will silently send [e-mail] to [e-mail] and you'll only figure it out by looking at your server logs for rejected mail.

In those cases I have to specifically alias that [e-mail] to the subdomain.

With this new Apple privacy subdomain maybe eBay will finally fix this.

Why would anyone entrust money to a company like eBay if they are this incompetent at something as simple as e-mail?

Because the world runs on incompetence, so it's ultimately unavoidable (best case, you don't know that something important that you're relying on is run incompetently).
