❓ Where I can contact if bot not working

? You can contact here

❓ How many members @MembersScraperBot can add

? It depends on several factors. Remember, the bot cannot bypass any Telegram limitations. So as there is a limit on how many members a user can add, the bot will stop after adding that amount. So it's better to use a fresh old Telegram account. New accounts may get banned from Telegram soon. And you can login to another Telegram account if any account gets banned or limited in the bot. The new login will replace the old account login. On the channel, you can add a total of 200 subscribers and on a group you can add until Telegram checks your account and bans it or limits it.
