He could use any remaining funds for rent/mortgage until the fund is empty and be in the clear.
His vague wording of the "legal fund to seek justice" allows him lots of leeway. He wanted to (and was successful at) deceive people into believing it was to pay the lawyer's fees for an expensive lawsuit against LPS. By filing for free in the kangaroo court that is the HRTC, he avoids actually having to spend it for this presumed purpose.
Now, he could get away with doing all sorts of shit if his IQ was above room temperature. This could include donating to other troon's GFM campaigns (e.g. "boohoo need peen chop", or even "boohoo muh mentals"). The money is technically being spent on seeking/acquiring justice, and could be twisted enough to be considered a valid use. Shit, he could probably Google a bunch of legal questions, say each query cost him $5 of his time, and claim it was his way of "seeking justice".
Using the fund on new equipment/furniture he never had before, on Doordash for two, on illicit drugs, or anything else? Lol no.
