Firstly, the issue of fake accounts - there are tons of them. The only way I have found to trust a Telegram channel is to see its posts shared by another trusted channel.
Next, the scammers. Telegram seems to be doing fuck all to prevent bot accounts. I regularly get private messages from scammers. Delete and move on. Telegram lets you delete the convo from their end.
And of course change all of your account settings to private.
