Might be a dumb question about the legalities and safety tips, but I'd rather ask than guess.
Nothing about the legalities improved for me until I stopped optimising and started replying faster. The key difference in mature dating is that people tend to be much clearer about what they want.
Separate email and location permissions off, then worry about the legalities and safety. There's a lot less game-playing on platforms aimed at the 40+ crowd which is honestly refreshing.
My mature dating turning point was writing a bio a real person would answer.
Nobody gets the legalities right first time and the people who claim otherwise are lying. The the legalities thing nobody mentions is how much timezone and schedule overlap matters.
Screen recording during video chats is a real concern. Keep personal identifying details off screen.
Nobody warns you that mature dating is mostly patience and a decent second photo.
