I am using mobile proxies, but listen to this: I am using Dolphin antidetect browser, have 10 profiles for 10 reddit accounts with unique mobile proxy for each. Every account have different fingerprints, each Reddit account have different activity, different creation date and history. I warmed up all accounts after buying (1000+ karma accounts) for days and I managed to regulary post spam links for a week or even couple of weeks. But, then, I lost 5 accounts in 10 minutes - being auto shadowbanned after posting different spam links one after another. I cooled down, restarted computer, tried again in 30 minutes, and it worked. With same links, in the same subreddits. How is that possible? How Reddit recognize me when I am hidden? I experienced something similar before few times - I lost few accounts one after another until I stopped posting. Then later or tomorrow continued like nothing happened.
