Hello Ankit, sometimes i have been add some telegram group without my permission, so when i open the channel i can see a button on top as '' Report Spam and Leave'' and i directly use this button. I kindly warn you about that, if lots of added people use this button, your channel can be closed. I offer you to be carefull on this issue.
Regards.
Thanks for suggestion. I am trying to find those only who can provide targeted members. Related to my product. If you know anyone who can provide telegram members than please let me know.
