and add hidden rules about what transactions they will ignore ...
This one is a simple lie.
The codebase used for Eligius's policy is in my public git repository, and documented on the website.
"Transactions without a fee will be processed based on confidential anti-spam testing."
http://eligius.st/~gateway/faq-page/faq-5That's (very) obsolete information, and even then says it applies to transactions
without a fee - ie, begger transactions.
I'll see about figuring out who/how to update the page. The FAQ under it appears to be up to date.
