Definitely an annoying situation, I guess maybe you could try posting about the problems that you see with Snapchat, like with articles and whatnot, whenever you have a chance, and maybe just trying to get them to change their stance on it. For me personally, leaving Snapchat was a privacy and ethics choice - and anyone who wouldn’t respect that, good riddance. I only really have two friends myself. I enjoy it usually. I get to spend lots more time with them, and an exchange have a deeper connection. Its not for everyone though.
