It is possible to increase followers by manipulating social media with different techniques. But this is just as unethical, it is not beneficial. Because those who follow you without their consent will leave you when they realize this. Also, you can manipulate the system for a certain period of time, but eventually it will be understood and your account will be closed. All that effort you put into making money from Instagram goes to waste. However, you can get followers and make your profile look credible and reliable only if you consider getting a trademark Instagram username. What do you prefer?
