Pardon me, but this is a list of pardons given to pardoned people.

It's a play on Donald Trump, after watching a Liz Oyer video linking a very plausible pardon for sale scheme, I wanted to initially build a site that showcased pardons just by Trump, but I realized that would be partisan and not as useful.

I'd presumed this was a wordplay on Donald Trump.
