I am using telethon to scrape members from a group, I can filter out active and non-active members but when adding members to another group I mostly get UserPrivacyRestrictedError.
because of that I usually get PeerFloodError after few request. is there a way to get participants that does not have privacy enabled?
No. You can only find that out by trying to perform that action.
Telethon check if user has privacy settings enabled
