If people are not respecting your no, that’s not acceptable, but I’m not really sure what their poly status has to do with it (any more than their nationality, their job, the fact that they play video games, or whatever). I don’t think poly ‘legitimizes’ reaching a wider number of victims—being willing to date multiple people doesn’t give you a right to cross others’ boundaries. I suspect that in communities less friendly to polyamory, these predators would just stay single, or cheat on their partners.
