Telegram: Need Mass Invite from Targeted Groups

I have a channel and need someone to mass invite people from other channels. The maximum users I might want to invite is around 50K, but I understand that might take a long time and we can deal with smaller amounts at first.
Really need to find someone who can do this, please don't hesitate to PM.

Telegram limits channel invitations to only 200 members.
You can only retrieve the member list if you have admin; you cannot retrieve the member list from an opponent's group.
Some Telegram groups even have a "hide member" feature

The best way would be to create a new group and scan the members from the opponent's groups that do not hide their member lists. However, please note that this process will be time-consuming.


P.S. If you need assistance in seeding a group from your opponent, feel free to PM me. I can generate realistic chat messages and operate 24/7.
