# If I make an @user comment, then delete it, does the user still get notified?

Sometimes I write an @user comment, then delete it. For example, it might need significant editing, or I might subsequently think it's not important enough to leave.

Question: If I make an @user comment, then delete it, does the user still get notified?

I'm just worried it would be annoying.

And for extra credit (depending on the answer to the first question):

Question: If I make several @user comment, then delete them all, does the user get notified each time?

E.g. if I edit multiple times.

Yes and no.

As you make an @user comment, the user will be notified.

As you delete the @user comment, the notification will be purged from the user's inbox.

But as with all things software/on the internet, there is a small delay (not to mention the human delay). This causes a race condition that it is technically possible for a user to open up his inbox, read the first few words of your comment, click on the link, only to find out that the comment doesn't exist.

• Corollary: if the user is online at the time and watching his inbox, you may annoy him by doing that. If the user is offline for a while, then he won't notice what you did. Jan 10 '13 at 9:22

• What happens if I change @user to @user2? Will both be notified? Jan 10 '13 at 11:42
• haha I get the warning that only one user will be notified, although none of them exists. $\color{red}{\text{(bug)}}$ Jan 10 '13 at 11:44
