it would save time for players and the pro team itself if there was a kind of pokemon trash can working as follows:
discarded pokemons would go to the trash and could not be removed from there by the user, only after some time (say 2d) would they disappear from the player's personal trash and go to a kind of lost and found (would disappear from there too, after time), where any player with released trade can redeem this pokemon.

 

I already deleted several pokemon that could interest others but I couldn't get rid of it in the exchange chat

 

the player would not need to make a request to recover his accidentally thrown pokemon.
the staff would not need to be recovering pokemon (solution similar to reducing the level of pokemon)

 

maybe lost and found is really crazy, disregard it hahahaha
but the part of the pokemon trash can is interesting, for the reasons already mentioned
