Yeah, scammers are everywhere but Telegram only got popular because it is decentralized, so you can get a message from random people directly, not like to others where it can usually fall off in the spam folder or message request first. Not all are techy enough to go on these sections, so the chance for them to get scammed is still much lesser there.
