Even though I see where this is coming from I have to agree with Smaguris, the issue itself can be easily resolved by 3rd party screenshot programs and I don't see any way how it can make the game better.

As of now, Toribash makes .bmp screenshots which take lots of space. With the default 720p resolution they're 2.63 MB each, imagine having automatic post-game screenshot feature you suggest enabled 24/7 and here you have a cluttered hard drive after a month of playing the game. And even if we don't consider storage why would anyone want to keep thousands of dull screenshots?
Yes it can help at solving scam reports - but honestly, why would you care if users don't have enough evidence to prove they've been scammed? If they agree to play a non-automated duel that implies a risk of getting scammed, they should be smart enough to screenshot every chat message - just in case. As for hosting events - it's easier (and way more reasonable) to get a script that'd keep you updated with all info you need, including a list of players in the queue at the moment of the event's beginning.



speaking shortly, the majority of users won't need it, it will eat disk space, those who may find it useful should consider different ways of solving their issues
