Perhaps you’re correct. If the apps allow you to input/select content for parsing, then the admins/mods can do some tests/dryruns to see what is happening on the backend and block it, and nothing of value would be lost as far as HN and its guidelines are concerned. HN doesn’t allow bots or novelty accounts, and this kind of posting behavior as mentioned in OP is actively moderated against for breaking the guidelines of HN, so it doesn’t hurt to ask. The sites mentioned in OP may also have a way to request to not be used on domains that you own, as well.
