Hey, if you are trying to report players with screenshots I would recommend using gyazo or imgur, as you only have to paste the link to the screenshot instead of uploading a file.
Another alternative to Gyazo, or Imgur is Lightshot; it's very lightweight and works pretty fast however it's not the best regarding privacy.
This is correct. Also, if you report hackers, you MUST have video evidence and it has to be uploaded to https://www.youtube.com/ or https://streamable.com/ (Any other streaming site is also fine just no downloads) - Locked
