The point of finally is to run after a try...catch block no matter what happens. From the MDN
Note that the finally clause executes regardless of whether or not an exception is thrown. Also, if an exception is thrown, the statements in the finally clause execute even if no catch clause handles the exception. You can use the finally clause to make your script fail gracefully when an exception occurs; for example, to do general cleanup, you may need to release a resource that your script has tied up.
For further actions, you may consider blocking this person and/or reporting abuse
