I met a girl on a dating site. When I met her, she turned out to be much more beautiful than in the photo. Since then I like to communicate with people online, I met a lot of new people from other countries.
I had the complete opposite experience, it wasn't by any means a deal breaker but it does raise the question of when does it become unethical.
Nevermind fake accounts and attacks etc.
I think its a good thing overall but I do think the platforms need to do as much as possible to ensure safety
