The strikethrough isn't enough of a clue for you? I'm not sure what purpose not putting up the entry would serve. This way people know why there's no reciprocity for the recipient, otherwise they might be confused and think the recipient had done something.

What I don't get is why people are always deleting their stuff in this fandom. I have never been in a fandom before where things were so ephemeral. There's always at least one deletion from every challenge before six months is up.
