I'm a professional telegram bot developer. I developed many projects like this. I even got a complete solution like Telegram Scraper. Let's discuss the details
Hi, I have some experience, i think can help resolve your issue, please contact with me, thank you.
Relevant Skills and Experience
Java, android, web, some experience about telegram api
First thing to know about limitations of telegram are :
We can add max 30 messages at once but if you send all at once you will get blocked so we need to split up
Same goes while adding members to group/channel
This is as per official telegram limitations for each user
So now I have built a bot with following features :
It can get at max 10000 members from a group at random ( so resuse to get more) to a CSV file containing username,first-name,lastname,userid
Next you can add members from opponent group to your own group just by using both chat ids (adding 10 per minute to avoid blocking)
Next you can send bulk messages 10 per minute and the message will be personalized like you can have the four fields mentioned above for each and every chat so that it looks very personal and can also use emojis.
Next you can run multiple accounts and multiple instances at same time parallel.
Next you dont need to install even just download and use.
Next I have a bot that can remove messages like join,remove messages appear when someone joins or leaves group .this can protect your group' s privacy.
I built this based in modern modifications and if any modifications you require I can make I am just explaining you all at open .
Just before declining mine and accepting others just think if they know all these because most people don't even know telegram
I have made so many sales out of it and no one regret it because I am open and true
Now the bot is ready if you want to buy it just ping me.
Thank you
if you just need to scrapping people part I will give it to you for 50$
