I'm not a fan of mandos, but it depends a bit on the course and rationale for the mando.
Mandos should not be used to ensure safety, particularly the safety of non-disc golfers or their property. As others have said, many players won't abide by them, and even for those who know the mando is there, it doesn't stop their erratic shot from flying into the danger area---just penalizes them if it does.
Mandos to define the route on a hole, or separate fairways, are a little different. Certainly, many casual players will ignore them---just like they ignore O.B., rules, etiquette, and even obstacles (I've seen people give themselves 20' of relief from dense underbrush). So what? For the players who respect the mandos, the course is better for them. Assuming, of course, that the mandos actually enhance the play of the holes. And if, on a casual afternoon, the casual players are trespassing on another fairway, it's not a big deal either.
Some courses don't have a lot of these casual players, anyway. Others are overrun by them.
That said, I think it's much better to design holes where obstacles and O.B. define the play, and use mandos only where there is no other choice.
And, for God's sake, only use mandos that are unambiguous.
