What can you say about this??
Can you really believe a good project with good concept would forcefully invite you into their community without any prior notice??
This is the act of irresponsible spammers, they deliberately save our cellphone number to be entered into an unclear telegram group, we cannot do anything for this only the Telegram can repair the system
Good projects will never use the services of spammers like this to add members to their groups, good projects will have their own ways to attract investors
Those who use services like this are just SCAM projects
Maybe read the entire thread... You can easily adjust your privacy settings, so people can't add you to groups.
Someone has mentioned that a couple of posts above you.
Invitation without prior notice and done by bots? A BIG NO NO. To avoid those invitations to happen again, do this.
1st : Open your telegram account, go to settings
2nd : Go to Privacy and Security
3rd : Under Privacy, go to Groups then select "My Contacts" as Who can invite you to groups and channels
4th : Don't add any contacts. Just join your desired channel if you wish by getting their TG Profile link then Save.
Those invitations might be a part of bounty campaign or artificial growth of community to attract investors for selfish reasons. Leave those groups and report spam if you wish.
Now, I do think that Telegram should have that function enabled by default.
