&A private group is always a private group where only "invited" members can read and participate. If you have blocked a user, that user will not be shown to you in groups either, and the blocked user cannot write or "Pin" to you. You can block a user from reading and participating in the specific group, but Smiling X uses an algorithm to calculate whether a user should be blocked from the entire group if there are multiple members, it is calculated based on whether 5% of all members in the group believe that a user should be blocked, the user will be blocked when 5% of all members have requested blocking. If you are the owner/administrator of the group, you also decide who should be a member and you can block unwanted members It might also be a good idea to report a user, even if it is a violation of the law, stalking, child pornography/abuse, etc. then write a report on the link here and we will review the case- https://smilingx.com/Report?La=GB If SmilingX believes the report is justified, we will assess whether the reported user should be completely excluded from SmilingX.com
