Reddit shouldn't be the absolute owner of the content submitted by users.
And neither should you, nor anyone else here running a reddit scraper bot.
If users want to (re-)post their content here as well, awesome, but automatically scraping reddit to repost other people's content (which they then don't know about, and can't really interact with or control like it's their own content.) is just spam imo.
Create and post your own original content while letting others worry about their own content. People can make their own decisions, why should you have the right to override that?
