I can't imagine too many false positives.
I'd not come across the .cyou TLD before so thought I'd do a search, I found that ShortDot operate it and describe it thus:
The .cyou domain is crafted specifically for today’s generation of movers and shakers who have never lived in a world without social media or the internet... The .cyou domain is for the group of technologically advanced, eco-conscious, open-minded individuals of today. It’s for Gen Z and for those who thrive on memes and speak fluent emoji.
And email spammers apparently.
It's the app I've been using most but having more installed creates a conflict, constantly wondering whether I'm typing into the right one and whether something else could be better. Debate over, regardless of whether something else is better or not.
Simplify and get on with it.
