The proof of work contact form on my web site has a difficulty adjustment. I can it the annoyance adjustment. Any time I start getting annoyed by the volume of messages I receive, I bump up the difficulty.
I started off 5 years ago at about 30 seconds worth of hashes on a desktop CPU and now am up to 10 minutes.
this is how you do it

Proof of Work? Such stone age technology. Have you tried fixing the filters? /s
It probably adjusts only one way, as getting little messages is less of a nuisance than the nuisance of adjusting the difficulty?
In general, people are better at taking note that they're annoyed than at realising that they aren't annoyed.
Why not ask for money instead of hashes?
