Question regarding firebase rules

Question

I had a firebase code in sololearn which votes for some things (for examples programming languages). But I had to make it private because some users manually write the program and submit results with spamming and bad words.
Therefore I tried to solve that problem using configuring the firebase rules. Most of the rules are working but I want to know if the value submitted is an array.
For example
reference.update(["java","c"]) //valid
reference.update(true) //invalid
Many examples in google are not working

Now, are you trying to determine using the rules if the value is an array?
if so, maybe this will help

Sonic then most of the users will be blocked 😆. The best thing is to configure rules. So no extra work for mods . And also there is no way of finding the username of a user in my app
