I realize that when isolated group members have access to a shared/common channel with other group members, they are now able to send them a DM. I'm happy with both my paid & free (isolated) members having a shared general channel (which operates like a news feed in a facebook group) where everyone can discuss common themes, ask questions, etc. but at the same time, I also want to safeguard my paid members from potential spammy free members. And, this is especially important as my community is primarily meant to be a safe space (for my paid members) but I also want to have a general discussion channel where everyone can come together to discuss important topics (like a news feed on facebook) but with the protection of not being able to message anyone directly (like on FB, you can only DM someone if they are friends with you in the platform). Thank you
