I joined this, replied to the post, and now I'm being sent lots of creepy messages and dick pics from the men of the internet :/ Telegram has no option for "Only allow contacts to message me", it turns out. After lots of messages, they eventually offer to auto archive and mute people not on your contacts, but it's still fairly visible on the app. Perhaps Telegram should work on better abuse management before adding v…

In Settings / Privacy and Security / Blocked Users there's a "+ Block User" option. Clicking this brings up a list of all chats and people who have messaged your directly. Selecting a name blocks a user. Maybe even easier is pressing and long holding the name of someone who has sent you a message. In the vertical dots menu is then an option to block the user. I'm running v7.1.3 from F-Droid. I do agree though that an…

Yup, the former works! Took me a while to find it haha.

The hold + three dots thing isn't there on iOS sadly.

Even something like Instagram's message requests would be a welcome addition!

Telegram is amazing messaging app. It is so fast! When I travel by boat and my phone barely sees one notch of GSM service (not 3G, not even Edge) from the island on the horizon - Telegram is able to send and receive messages. Whatsapp and Slack can't even connect for hours after that. Another amazing thing is when I type a message on my phone - I see it on my PC the moment I press Send button. There's no visible dela…

>I type a message on my phone - I see it on my PC the moment I press Send button

I use some telegram groups and sometimes i'd start typing in phone before the message gets too long and i'd prefer to carry on the message in my laptop instead. It is so useful to have this feature.

Yes, Slack copied that about two weeks ago, with glitches between versions. Hope they will copy other features someday.

No mention of any kind of encryption?

Telegram keeps talking about how private and secure it is, but all group and private chats are not encrypted by default. Its end to end encrypted chats are very limited (only direct messages and only on one device) and rely on self-baked crypto. Their voice chat is also almost definitely not end to end encrypted, as I'm not aware of a way to do e2ee voice chat with many participants without linearly increasing bandwi…

> I'm not aware of a way to do e2ee voice chat with many participants without linearly increasing bandwidth requirements for users

This can be almost trivially extended from one-to-one end-to-end encrypted text chats: One peer picks a random symmetric key and forwards it to all participants over the existing encrypted and authenticated channel.

Afterwards, you can just use the most appropriate way of relaying encrypted voice data: Full mesh peer to peer, one party acting as relay for everybody else, using an SFU that relays incoming data from one peer to all others (without being able to decrypt it)...

> Telegram has also been exploited multiple times Source?

Here's one: https://www.zdnet.com/article/telegram-voicemail-hack-used-a...

This had nothing to do with code vulnerabilities let alone open-source in general. It was a social engineering hack relying on default voicemail passwords.
