Your quandary makes me wonder if this stupid app is also going to flag and block Georgia O'Keefe? Because the world needs a mega corporation defending all our good moral sensibilities.
I have little to no knowledge about what exactly the phones are doing, since I don't care to do much on my phone besides text and don't usually look up comics on my phone...
This is just so annoying.
They should give you an option to chose blocking NSFW imagery, not just splash it across the board. Not everyone on the planet who owns an Apple phone or whatever is a uptight about nudity and porn, or has kids. I feel they should give you an option to turn the auto-screening off if you don't want it. Or at least give a person the option to view it and judge whether or not they mind what's been flagged (I mean, it could be flagging non-offensive stuff, if it's anything like what Tumblr did.)
Sorry, I have nothing of import to help you with your problem, but I did feel like venting. It really doesn't even effect me since I don't own one, and I don't think I'm reaching enough people for it to be an issue...so...yeah.
