ACC tries to detect if you're using Firebug.
Using this same method, I found like 5 other glitches/loopholes, including...
1. Posting in staff-only sections
2. Removing people from another person's Private Thread/ Buddy Thread or deleting it altogether
3. Bypassing new member limitations.
4. Posting in a PT you aren't in.
5. giving people a 10 star + wifi rating (over 10 breaks their profile)
And I'm just a noob XD
If I can find all this in just a few hours I wonder what a real hacker could do.
