I've tried everything from just 50 up to 200, I never go over 200 because for the subreddits I use it is not required to be seen with more than that.
When we warm up accounts and farm karma we are focusing on Reddit achievements, comment and post karma as well as followers. When farming is done we have 100 - 200 followers.
We of course spoof and use high quality proxies. I have a warehouse in USA where we are using our own mobile proxies. We only post on phones, no browser.
The confusion comes from without upvote botting our accounts last basically forever, we very very rarely get account bans, but when we use any upvote bot we are banned 100% of the time after 24 hours, not sure why. That is only reason I come here, not competitor or to hate, but to learn. It was the case for us in Q3 2024, but since Q4 2024 - around 1 month ago we were okay, now the issue is returned. We think Reddit is detecting better again now or something. Not sure.
My theory is Reddit is detecting the inconsistencies in post engagement. Before upvote botting the accounts will have average organic engagement, then you upvote bot and there is of course a spike, this spike is unusual, they see where the spike stems from (views, upvotes etc) then that results in the ban. The only issue is how do you upvote bot without them noticing this spike, even if account is heavily warmed up
