Spamming is not only obnoxious, but a very weak example. Spamming is so error tolerant that if 30% of the output is totally wrong, the sender won't notice. Response rates are usually very low. This is a singularly un-demanding problem.

You don't even need "AI" for this. Just score LinkedIn profiles based on keywords, and if the score is high enough, send a spam. Draft a few form letters, and send the one most appropriate for the keywords. Probably would have about the same reply rate.
