This is nothing but a baseless and possible false accusation
The linked image doesn't prove anything nor does your post provide enough insights to what you're trying to accuse PD of.
Considering your trust i would only call this a false accusation. If it's not, please make a proper post in the right section.
I hope your problem gets resolved (if there is any)
