That's an interesting question but I'd assume not, although it might be open to discovery. It would be super improper for a judge to make decisions based on things like this that are unknown to the debtor, but a trustee isn't a judge. She represents the United States in this, the bankruptcy estate itself (a separate legal entity from the bankrupt) and has some duties to the creditors as well.
She isn't the ultimate decision maker, though, and I don't think random tips are evidence as such, unless she actually files them so the judge can use them. I am not sure they'd even be admissible without the source of them available to testify and give a foundation for their admission.
I could see DSP making a Hail Mary play blaming the situation on detractors, claiming he was prejudiced by that fake creditor at the 341 meeting and otherwise that there's a conspiracy against him. But he'd have to pay a lawyer to do that. Sweaty naked dudes are much more important to him than that apparently.
