He asked for 45 ultra balls, in return I'd get an Eevee. He left after I gave him the balls. The video is too big to attach though. Is there some other way for me to send it to someone? Thanks.
Hey, uploading it to YouTube is the best way to get it to us when the file size is too big. After you've done that, either report the player in the player report section here on the forums or report it on discord in the punishment-report section.
Report the player here http://forum.pokefind.co/index.php?categories/punishment-appeals-and-player-reports.21/, as suggested by Jadyns you should upload the video to Youtube
