I'd look under that client/Topic() stuff to see if there's anything that can be exploited.

The only verbs under client/Topic() that is remotely close to any admin verbs is when I call admin help under it, but thats about it.
Don't know what to tell ya, don't use second-hand source.
They're all lying to you. There is a BYOND exploit in the default behavior that could potentially do damage, but the case here isn't likely to have anything to do with that.

It's likely either your own stupidity or the host is collaborating with this individual.
Topic is usually the easiest way to hack any byond game or dos it.
