Like, someone getting a 100 mil bounty out of the blue is incredibly unusual. They probably didn't want to raise too much attention to that, and thought that 100 mil would be good enough to signify Luffy's threat, while also not being large enough to raise too much suspicion or cause too much of a ruckus.
Like, Oda even says that if Crocodile was an active pirate, his bounty would have at least doubled if they knew about Baroque works.

Doflamingo was defeated by two pirates and both were given 500M as a result, which is pretty legit imho.
