Is a link like "t-do.ru/joinchat/*******" safe?

Question

Phishing

They sent a link of this kind "t-do.ru/joinchat/*******", an invitation to a Telegram chat.
1. Is this kind of link safe?
2. And what can the author of this link see, that I subscribed and that's it?
3. And I'm also interested in the question: a link of this kind for an invitation to a chat - is it the same for everyone or unique, and for example, by my subscription can he see who I am by the one to whom he sent this link? That is, he sent me an email, I signed up, and he will understand that it's me and will my Telegram profile be connected to my mail?

Answer 1

1. In the sense of "safe"? If you go through it, the cabinet will not fall on you, and the backdoor will not climb onto the computer. Regular link to invite to chat;
2. If you subscribe, then yes, otherwise how can he understand whether you see messages or not?
3. It is the same, it is a link to the chat, and no one is interested in who will connect to it there. No one will generate unique links for the sake of some random person.
Stop paranoia, my advice. It only gets in the way.
