Is nitro hard to get on discord?

Honestly I think it's really easy like I was talking with someone on discord in private massage for like 15 minutes or so and just having a normal conversation and having fun talking when out of nowhere they give me nitro and tbh I don't even know what it does or really even care about it but when I told my friend on discord they were saying how unfair it was how they had to talk to weirdos just to get it like is it fr that Serious?
