Isn't that related to the use of @ tagging? The plugin reports on the use of the quote feature in a post, and it doesn't require any extra posting. I'll try it out on one of my SMF forums, and see how it works.
You get notification if someone posts your username. Since the bot reads trough the "recent posts", if someone edit his post after he has posted it and add your name, you won't be notified.
Otherwise, for posts like
yourname,
@yourname,
"yourname", quoting you, etc. you will be notified.
AFAIK if your username is in a hyperlink format, the bot cannot read trough links and you wont be notified for this input.
