I appreciate your response and your attention. I will investigate sorting by read time when I get home. My guess is that it will work well for me.
Regarding your hesitation to reject users based on not reading posts, I just want to note that I have been using this feature for some time now and 100% of those users have been spam. I hope you at least consider auto rejection as a configurable option.
AI spam filtering would be amazing.
I really appreciate your product.
