To be fair they rejected it because his "report" consisted of a link to a profile where he claimed to have exploited the bug, without any explanation of what he actually did. If he had at least given a rough indication of what the exploit was I am sure they would have reacted differently.

Your point being? He doesn't explain the exploit at all, he just gives them a link to some profile he claims to have exploited (which already violated their ToS).
That doesn't automatically make it ok for him to go ahead and exploit someone's profile for attention (for the 2nd time). He wrote a lazy report and knew they did not understand him. He could write a more detailed report and tell them that they have misunderstood him. Or he could write one in Arabic and ask them to get help from one of the Arabic-speaking employees.
After two messages back and forth, he says "i have no choice other than report this to mark himself". He did indeed have many other choices but he jumped straight to posting on Mark's profile which he knew will create a global shit-storm.
It's clear he wasn't very reluctant to posting on Mark's profile anyway. He was just waiting for them to ignore him so he can drop his "i have no other choice" line and go ahead.
