There are no excuses. Facebook should expect that hackers with english as a second language (or not even that) will find bugs in the system and that they will not be able to communicate the way the Facebook team expects.
They should stop finding excuses and start to focus their efforts on making sure that people with no communication skills can report any bug.
Suggestion: Facebook could create a new "Facebook_security" system, which can be used to report bugs. The system would have the same production version, but the terms and conditions would be flexible. It would be used only for security purposes, and if someone finds a bug, they could record the exploit and send to the facebook team. By doing this, they would make sure that any type of bug could be reported.
