Features :

Note :

1. Adding feature will work only if the account given is in both source and target group
2. Your account will be blocked if many people report you of spamming. Keep that in mind while broadcasting
3. Use wait time accordingly so that telegram won't block you for spamming/flooding/exceeding rate limit.
