You will get OP for 30 minutes , you will have OP for the same things as helpers (you cannot grief or break the rules in any way) if you break the rules you will be IP banned without a refund.

Rules for the AT apply to you as well.

Recommended usage:

Testing commands or creating something inside a state with commands.
Harmless trolling
Testing features in functions and similar things

Just use this sensibly. Can be fun to a certain degree, but after some time can become useless. Like a ticket to a theme park.
