I completely understand, and I do believe that sharing contacts might be discouraged by the mods.
There's also the aspect of rapport. I believe that when a person develops a communication relationship with an SP, that cannot trivially be inherited by a 3rd person.
Finally, in the interest of ethical punting, it's probably best practice to maintain confidentiality for continued patronage with SP's.
BUT, having said all of the above, if there were a way to i. Share contacts, ii. Transfer rapport to a 3rd person, & iii. Not breach confidentiality, that might be a topic of conversation outside of this forum. I don't suspect it's outside of the guidelines of this forum to connect with fellow punters offline, and be introduced socially to each others' networks.
ps1: It's quite unclear why the personal messaging is blocked for some of us. Perhaps it's linked to activity analytics, in which case it would be good to get an understanding of the minimal qualifying criteria ...
ps2: Waiting, is this message going to get me banned ...
