I'm not saying I do this but if I were as smart as I think I am I would have given a Gmail example rather than the example you've given to avoid bots just looking up my website and starting to bypass my setup... ;) ;) ;)

Also, spammers generally don't seem to be going to the effort to apply regex filters to the data they've scraped...

I self host email, and I have never gotten spam to any email "constructed" from the domain, other than random attempts to things like "[e-mail]" etc.

But the email I used to interact with the Linux kernel mailing list I had to null route after a while, it got so much spam. I used a throwaway for just that purpose of course, so no big deal.

By far the worst one is always going to be something generic like contact@, but my email provider is very good at filtering out those appropriately. :)
