What makes you say that?
Plus there's the whole issue with your app sidestepping reddit's "delete", "remove", "edit", and "private subreddit" functionality. Those things exist for very good reasons and are nothing like what Social Fixer did.
But I'm really curious about what you said regarding sidestepping delete functionality. How do you view search engines indexing and caching of reddit and other sites? Does the Barbara Streisand effect apply? I think that the issue is way more nuanced than no "sidesteppping" allowed.
One of my main motivations for creating unedditreddit was noticing that there was a lot of baloney moderation going on. Cabals of power users can censor quite a bit and it is completely opaque as to who deleted something and for what. I think it could damage the community in the same way digg vote rings used to.
If you can't, please stop releasing idiotic extensions that bring individual human beings more suffering than benefit.
