You can't expect much from developers that think it's a good idea to limit tags to only specially selected categories.
If they at least didn't do that, then they would probably have the gumption to implement a spam filter of some kind (with the amount of material these spammers are providing, you could literally train an AI to do it for you, and flag potential spams for easy handling. Not that hard to do)
But hey, that's just my opinion, a very good opinion.
