Blocking users are able to discover you have blocked them through emojis.

Recently blocked an individual on a server who was just too obnoxious. I did this along with three others. Things were well for a month but now he apparently was able to find out when he attempted to leave an emoji response to one of our messages and was informed he could not do this. So he's now been able to figure out who all has blocked him and is stirring up a new storm of whining over it. Would be nice if there was a method whereby a blocked user could still leave emojis on messages but not have them shown to the individual who blocked them.
