That sounds nice. I use bitwarden's "plus addressed email" generator I think it's called, the downside being that I need to specifically blackhole anything that bypasses the plus-addressing, or it'd be easy for anyone that actually looks to bypass.

There still is the chance that some spammer will figure out that "blah+any-random-string" works for my email, but I'll deal with that if someone bothers someday. I'd just need to add an allow-list or something probably.
