Generate an Automation for writing messages on social media platform

Generate an automation that writes three different messages to three different types of users on a social trading platform, based on their actions. For instance, users that follow and unfollow me. So, if for instance 30 new users follow me each day, I want to write each of them a dynamic message saying something like: Hey [@name], thanks for following me. You can see a video about me to learn more here: [login to view URL] [name] is a dynamic variable, which is the name of the user following me. I want to be able to change the exact wording of the sentences myself. Similarly, I want to send users that unfollow me a message, and also, I want to write a third type of message to a third type of users. All of the messages include their name as a dynamic variable, and the script should check that a user should only receive a message once. So, if the users have already received a message, they should not receive the same message again. So the script will probably generate 50-200 messages a day, and it should include a pause of 10 seconds between each message, to make the messages appear like they were written by a human. This may be done using Python or tools like Katalon or Selenium or a similar automation tool. Please let me know your preferred technical solution when applying for the job. IMPORTANT: These action must taken on a social website that requires a login with 2 factor authentication which I will have to do myself. The site also has a Cloudflare protection check when logging in to assure that the user is human, so I will probably have to log in manually on the platform and then run the script after logging in. Please advise how you want to solve this issue related to the login. If you want to take this job, you will have to set up one or two accounts on the social media platform to check if all of the above functions work well. When the job is delivered, all source code should be delivered to me, and I would own the source code after the project has ended.
