I found an old thread about Freshdesk in the SpamAssassin Users archive [1]. This supports (confirms to me) that this is what happens.
I object to this type of behavior and would like for whomever is doing it to be unsubscribed from the SpamAssassin Users mailing list on principal.
Maybe give them one chance to come forward, admit the error of their ways, and to promise to cease and desist immediately.
