Since the production version is using a default label weight of 0.5,
previously two users would have had to label the same comment Exemplary
for it to actually activate. This will probably be fairly uncommon so we
most likely don't want it to work that way. This reduces it to 0.5 so
that one label will trigger it, but it would probably be better to
specifically set it to the default label weight if that's feasible
somehow.
