Looking at the edit they made one massive mistake anyway, they change EOS for 15.04, so, it is still off topic,

I would reject and leave a comment for the OP, comment something like 

"Please don't just change the version, we are aware you are using EOS a comment was left directing you to the EOS stack exchange but here it is again https://elementaryos.stackexchange.com/, in-spite of your edit you STILL changed it to a version we do not support, 15.04, so your question is still off topic and will remain closed"

This is exactly what I did do and the edit is now completely rejected.

That edit is rubbish anyway and the OP did not even bother to post at EOS stackexchange or check what we support, don't let it bother you, this will never be reopened.

If they try to edit again, go to chat and tag a mod or flag for them to come and delete the question permanently (if they can).
