Absolutely will cause a lot more spam to go through. But why is that the custom written moderators tool/bot fault? Why isn’t Reddit the company doing more to stop or combat spam/bots? Why keep doing their job for them, for free?? If it’s so damn useful (and BotDefense is), then Reddit should be doing it, or I don’t know pay for that service?!
Because … You can say to tech illiterate investors: "hey look, look at all the activity that goes on in my site"with not much scrutiny and inflate those rookie numbers up.
There is no much incentive, in the capitalists sense, to deter spam or trolls, fear mongering and explosive comments, clickbait journalism, etc etc etc … for owners of any online outlet, it’s all in the service of ever growing traffic.
