Block Rematches

Why is it that basically every game in existence that has the ability to rematch has figured out you should have a setting to automatically block it except for chess platforms? There's zero excuse for why a company as big as this doesn't have the basic functionality to turn off somebody's ability to pester you after the game like they are entitled to your time.

Honestly when I searched this up (I'd switch to lichess but they also don't have the ability to deny rematches) most the forum posts were just "why is my enemy not accepting my rematches??1 THEY SHOULD HABE TO ACCEPT". Because I don't know you, I don't want to play the same player over and over whether I won or lost. I can make it so my literal friends cannot request matches with me, my FRIENDS on the FRIEND'S LIST, but "girth_crusher_69" can force me to see his notification for zero reason. Like 1/3 of the games have a rematch request, I can't imagine the numbers on if they get accepted are staggeringly high. But regardless of what they are, there's no disadvantage to having this feature on a site with random matchmaking. If other people want to spam rematch requests they should be able to have the default on setting for it enabled and go on their merry way. But I should be able to turn it off.

They're simply not interested in the customer experience. This suggestion has been made over and over and over again in the forums, and suggested to Chess.com directly. It's a trivial amount of code to implement, but Chess.com cannot be bothered. I refused to subscribe over this issue alone.

Where, exactly? I don't see an option to block rematches in the iOS Chess app in Settings > Notifications.
