If you mean Reddit's Personals, a major difference is that the posts don't use pictures--and it's not like the posters use their first and last name as their username or anywhere in their post--so hopefully that'll keep it safe. After all, the main personals section has "148,372 readers" and right now, as of 11:57 PM Eastern Time, "1,946" are logged in. https://www.reddit.com/r/r4r/
