It's a basic mistake to operate on whole netblocks and not individual senders. It's like you would ban all citizens of a particular country X from coming to another country Y, because a lot of people from country X are terrorists.
If 99.9% of people from a country were terrorists, then you may allow someone in if they're not obviously a terrorist, but you'd certainly keep a close eye on them. Trusting someone just because they say they're not a terrorist would be too dangerous.
That's the equivalent of putting their mail in the spam folder. You're not rejecting it, because you're not 100% sure, but you're almost certain it's bad.
If you rejected it, the recipient could do nothing, but because you put it into their spam folder, the recipient can find it and choose to whitelist you.
As I've said before, if someone uses a gmail account (or other free cloud account) for important business email, they should at least giving their spam folder a cursory check every few days.
You have to understand that these netblocks are immensely bad, and there seems to be no abuse control at all. They're not just so-so - they are really bad, and the spammers change IP addresses frequently, which means that you can't assume that an IP address from the block which hasn't sent spam before won't send spam later on today.
The best thing is for you to move to a hosting company which actually takes abuse seriously. It's pretty pointless arguing about it - it's the way it is. If you use a spammer haven to host your emails, you're likely to be blocked, so don't do that.
