A system for checking false reports?
The team in charge of handling reports investigates chat logs and the activity on the account being reported. So while many warrantless reports are made, it’s very rare that those reports will lead to a suspension or ban because all reports are looked into by a human being.
I’m pretty sure you can report that mail for threatening you.
For once you have tasted flight you will walk the earth with your eyes turned skywards,
for there you have been and there you will long to return.

Anyone can /report anyone for anything. ANet doesn’t act unless they find something that violates the TOS. It happens to be against the TOS to misuse the report tools, which means people who deliberately use reporting to try to punish or coerce others (perfectly fine to report if you aren’t sure — ANet pays people to investigate and be sure; you don’t have to).
tl;dr the OP has nothing to worry about.
