Keeping for Memories
Just so you don't miss out on all the fun you've had in game with friends or any humorous event or awards you've gained, taking a screenshot of the moment would be one of the best decisions you can make as you can look back at your memories.
Screenshots can be useful as proof against or for a claim. Most of the time, you can't report a player simply by the default report GUI in the menu screen. Writing a small summary of the report isn't exactly proof. Reporting to the creator of a game or on Roblox official contact email with a screenshot is the most you can do to show proof of anything inappropriate.
