I think "deactivate"(if there is such option) would be a immediate solution. Remove it seems a bit unfair with those who already solved the kata, they will just loose their solutions.

IMO the right way would be to disable the 500+ solutions rule for admins. Thus avoiding future katas to get stuck like this.

I already sent this suggestion to codewars. Let us see what codewars admins will suggest.

It's necessary to specify if it is possible to have:

• empty array
• length == 1
• no numbers array elements

As joh_pot said you are using return in the way that the execution of your method just finishes.

For others questions/answers I would recommend you to take a look at the markdown spec, which can help you to write answers/doubts in the correctly formatted way.

Maybe the description could be improved a bit. What do you think about an approach with a more concise desc plus examples?

e.g:

Check to see if a string has the same amount of 'x's and 'o's. The method must return a boolean and be case insensitive. The string can contains any char.

Examples input/output:

XO("ooxx") => true
XO("xooxx") => false
XO("ooxXm") => true
XO("zpzpzpp") => true // when no 'x' and 'o' is present should return true
XO("zzoo") => false

pretty sure admins are able to fix this.
