I found out that when you Alert a Moderator with something like this
and press OK, you receive an "Internal server Error" (sorry, I did not take the screenshot).
When you try again to submit the alert (since i got "Internal Server Error" i do not know if my alert was raised or not), you got this strange message, pretty confusing, which i guess means the alert was already submitted (despite the Internal Server Error)
Seriously, what is "that 0"?
Now is him?
I cannot do anythig else than to try to laugh about all these bugs/flaws
