The spell, upon the first hours of release, only teleported other players and did not teleport the caster, it also gave no delay time, potentially making the caster obtain 9 million Magic XP an hour. This was announced as a glitch and some people abused it, and got their accounts rolled back or permanently banned. This has since been patched.
Completion of My Arm's Big Adventure is required to cast this spell. It is also required for other people being teleported.
