@alexhammy @researchfairy @signalapp We are aware, and working on new features to help address. In the meantime, we provide information in groups and profile details that enable you to see whether you have groups in common w/someone, whether you've ever chatted 1:1, etc. This will work to distinguish a new "Mike" from the "Mike" you speak with frequently. See more here, in the "How do I know this person is who they say they are?" section https://support.signal.org/hc/en-us/articles/6712070553754-Phone-Number-Privacy-and-Usernames
