In my opinion, spar hats are supposed to represent skill. Back then, when somebody hit 6k or 10k spar wins it was a big thing, because they were actually decent sparrers and everybody was rooting for them. These days, it seems like somebody new hits 6k spar wins every week. Also, there are people with 6k/10k spar wins who either boosted to this point(I could name a lot), or are... absolutely horrible at sparring. Or both.
I voted no, because I believe that only people with skill should recieve them, and I don't see a lot of those people around anymore.
