gollark: I actually was able to find this "jmwloup5110" person's LinkedIn account by using the advanced technique of "putting their username into duckduckgo". It looks like they do actually work on... computery things, and not recruiting somehow. This is probably not actually a problem.

gollark: They haven't done any. They just said they were in the air force. Lots of introductions talk about jobs.

gollark: We would probably notice people doing recruitery things anyway. This is pointless.

gollark: I'm sure people can be in the air force and interact in good faith on discord.

gollark: Do you know that this isn't just a regular person who is also in some sort of army thing? Prior experience elsewhere or something?
