    Hey guys. I am a computer engineer and currently focus on automation using python. I'm proficient in Text Mining. I have built bots to automate shilling on Telegram, by bulk messaging selected groups, as well as bots to add unlimited members to channels or groups. I can also use the 'shilling' bot to advertise for you, for how many hours as you like. My main focus here is to sell these bots to interested clients, which will help them create value. So, if you are interested in building a big group of fake members (with low drop ratio) or real members, or in an automated marketing tool that handles the messaging to your desired groups, please contact me.
