Currently we don't force TURN, so in practice this means that voice packets go direct between the clients if possible, and so the IP addresses of the clients are necessarily exposed to each other. However, this is utterly trivial to fix: matrix-js-sdk already exposes https://github.com/matrix-org/matrix-js-sdk/blob/96ba061732bc3b5e748719072356d562e52097ba/src/client.ts#L297 https://github.com/matrix-org/matrix-js-sdk/blob/96ba061732b... and we simply haven't exposed it as a setting in Element Call yet. I've filed a bug for it at https://github.com/vector-im/element-call/issues/251 https://github.com/vector-im/element-call/issues/251 - thanks for bringing it up! In terms of moderation: this is no different to moderation in Matrix as a whole, where we're already busy working on shared greylists (MSC2313 and friends) - https://matrix.org/blog/2020/10/19/combating-abuse-in-matrix-without-backdoors https://matrix.org/blog/2020/10/19/combating-abuse-in-matrix... has more details at the end.
