I have quite a sophisticated operation (web, mobile, jailbroken iPhones, 5G Verizon proxies, self-upgrading reddit app coherence, ML on survival vs bans, full TLS proxy for coherence, running account linking modeling+coherence modeling)
I have ~200 accounts alive at any given time. My 5-day survival rate for first comment is about 5% on web. Mobile I'm close to operational, just ironing out final production kinks.
- Big/generic subreddits = higher ban probability
- Mentioning any brand = higher ban probability
- A greater number of spaced-out account setup events = lower ban probability
- Clustered setup events = higher ban probability
My data is slow to accumulate. I have occasional survivors. As they accumulate, and the bandit assigns accounts to exploring the missing vector space, evidence will accumulate and reddit's algorithm will show through. My current theory: topic interest. Reddit is serving a feed of posts, and reddit predicts our probability of clicking into each thread. The more humanly we behave (digging into subreddits within our topical interest area) the more reddit believes we are human. Especially with video dwell time; scrolling through videos is being used as evidence of topic interest. It's one big graph with embeddings. The algorithm serves us content, and measures us against our own interests.
