Once upon a time, when the earth was green and unicorns roamed wild, AN (or TV as was) had a full set of reaction emojis and the names of who posted them appeared to members.
Then certain members started "emoji stalking" other members (adding negative reactions to many posts), this, of course, led to the victims returning the favour. It actually got quite nasty!
We reduced the emoji set to only the "positive" ones, members complained.
We removed all the reaction emojis, members complained.
There may have been some other iterations too (age is setting in and it was a while back - I think the whole trail is in the Support forum somewhere).
Finally, we settled on a pretty full emoji set but anonymous to members (hence the "Somebody" moniker).
Members still complain, but the instances of emoji-stalking do seem to be well down.
Staff can still see who posted emojis, so if you think you are being stalked hit the Report button on one of the posts and tell us.
