Help tracking down TO pokemon maybe?

I have no clue how much data is available for something like this. But also privacy concerns. Maybe an account setting on the website to opt in or out of this, off by default?

But some players like myself maybe found a rare shiny they regret trading away ages ago. Staff can tell you who you traded it to but from there, it's a misery. Maybe a way that players may see their trade history on the website staff seems to have access to with info of the pokemon forms and so on for it. And if the pokemon still exist hasn't been released you and the user has the option turned on you can see who has that pokemon of yours now and maybe contact to work out a deal. I know there's quite a few people that have an urge to track down a long lost friend.

And in my case, if that rare pokemon of yours dead ends to an account that seems to be banned if it's a permanent ban we can maybe work out a way to get that OT back from that perma banned account with some fair exchange in some way? Really really rough idea staff might have better ideas about. In my case a rare OT shinyJynx i caught and traded for nothing and want back lol I posted for staff and they told me the player i traded it to, but said player's account shows suspended on forums and no reply to message towards that account for over 2 years now XD Maybe I'm just too sentimental.

Again not sure how much data is available for this, could all be a fools errand here as they say, and don't really want to increase work load for any staff to look up long lost etc.
