Content of a reply to sci.electronics.repair and "Terms of use" for eternal-september.

Eternal September is my news host.

I have no difficulty sending a message to begin a thread.

An initial attempt at replying to a thread is often not accepted by
the server.  A filter on the server finds something in my reply
violates terms of use?

I'm happy to remove or obfuscate email addresses and links.  Even so, a
reply can be denied.

Is there a deterministic way to make a reply acceptable?

Thanks            ... Peter E.
