Personally I never give red rep, only grey, because I can never be sure if I'm contradicting an opinion, tone, or just facts. I've been tempted to give red once or twice, but it's just not worth it.
I don't have a lot of rep for my posts because many of my posts are just "great robot! I have some questions...", because I feel like giving compliments isn't really a wasted post.
Students are the ones who need the red rep the least, especially because many times they just don't know any better. The killers are the "mentor built robot blah blah" kids who just picked that up from their own teams. I know my team has had a huge bias against powerhouse teams for several years, and only recently has the leadership been able to lessen it. I can see many of the students, who are great in other ways, mess up by repeating that sentiment online.
