But... why?
The whole point is that the profiles are real people to network with professionally. The second people know that a profile might be a corporate bot, I feel like the site is done.
Besides, just have a python script that generates generic guy names and picks 10 random IT/ business skills, plus a 30% chance to add "synergy", "go getter", or "team-oriented", and you'll have recreated the same effect as your LLM, and saved yourself 40 million.
