Comments players

Not sure what you mean by sending comments to players that are not messages. Did you comment on their activity / achievements, screenshots, or videos?

Even if so, I don't believe there is a history of comments you've made.

once the messages are deleted then they cannot be retrieved my friend

Sorry buddy, as previuos ambassadors says, unfortunately this couldnt be possible if they are erased.

I did not say messages but comments that we give on a game or directly to a player. These comments are not erased, they are public. I would just like to find those players to whom I sent comments. Thank you

To my knowledge once you delete a message, its gone.
