Exploits of any kind are not allowed, not even to fight others who use exploits. You should report them to Funcom using the procedure described in the official server rules:
Since your forum account is new, you might not be able to send a direct message yet. Here’s how to deal with that:
NEW FORUM ACCOUNTS: Please be aware that newly created users can’t send private messages until a certain threshold has been met, which is to read 5 different posts, 30 different messages, and spend 10 minutes logged in. This is to prevent automated spam.
Good luck.
