BTW, this tool does not mass apply or create fake resumes, what it does is to use your data to create a resume that gives you a fighting chance against ATS systems.
I don't agree about escalating the arms race. To get a fighting chance against ATS systems you need to go around those systems, not try to trick them or get some small percentage of resumes through them. Like I wrote already, applying for jobs with online applications and sending in resumes in response to online posts -- whether tailored by AI or not -- describes a terrible strategy for getting a job. You can optimize a bad strategy and try to outsmart the ATS systems, or try a better strategy.
