I suspect that I'll be told that this is impossible or not going to happen. When a user is reported to the mods via the report member link on their profile page, could all their posts be hidden pending a review by the mods/admins? If the report is a malicious one then the one who did the report could get a bollocking with a warning or infraction. I don't know if it would also be possible to temporarily suspend the reported user as well.
Let's say this happens and I report you. All of your posts will be hidden until a staff member reviews it. Not a good idea because it can be abused. There is an Ignore button you can click to hide all posts made by someone but that's limited to your account only.
