You’ve not stopped abuse, you’re just making people pay $50 for it. I wanted it for a legitimate reason (my own subreddit populated by a popular disabiliy news blog). But $50 is mental for one feature. Reddit has complex algorithms to deal with the abuse..
If you want a closed-source free plugin for Reddit, then learn PHP yourself, and make it. One staring this plugin is childish, and frankly with an attitude like this, I am glad you aren’t supplying content to Reddit.
Otherwise, you can pay these fine people money for their hard work in supporting Reddit in the only way they can. I doubt you work for free, stop being ungrateful for what they DO provide.
